Thundering onto movie screens in color and CinemaScope in the Fall of 1960, Dinosaurus! roared out an invitation for children all across America. Prehistoric monsters were a favorite subject for kids in the 1950s, an interest popularized by Natural History books, dinosaur toy sets and TV re-runs of movies like King Kong (1933) and Godzilla (1954). Yet the movies produced in the previous decade featuring dinosaurs can be numbered on one hand. Universal's 1957 The Land Unknown featured impressive sets of a steaming "Lost World", but its dinosaurs were pitiful puppets or men in ill-fitting, anemic dino costumes. Baby boomer kids wanted their dinosaur movies, and Dinosaurus! delivered the goods.

The simple story finds a pair of enormous monsters, a Brontosaur and a Tyrannosaurus Rex, dragged from a freezing underwater sandbank off a small Caribbean island. The handsome contractor Bart (Ward Ramsey) must deal with panic on the island when lightning brings both beasts back alive and kicking. In addition to saving his pretty girlfriend Betty (Kristina Hanson), Bart must deal with the villainous local strongman Hacker (Fred Engelberg), who overworks and mistreats his young ward Julio (Alan Roberts). While the islanders flee to the safety of an old Spanish fortress, Hacker stays behind to claim another prehistoric survivor dredged up from the lagoon: a genuine Neanderthal Man (Gregg Martell). But the inquisitive Julio finds and befriends the Neanderthal, and the two of them take a ride on the back of the newly revived Brontosaurus.

Dinosaurus! marked a change of pace for the producing team of Jack H. Harris and Irvin S. Yeaworth, who two years before had made a big splash with their Pennsylvania-produced independent hit The Blob (1958). Philadelphia distributor Harris found Yeaworth in charge of a group of committed Christian filmmakers working on a farm/studio /quasi-commune in Chester Springs called Valley Forge Studios. The Blob featured a hot young New York actor named Steven McQueen and generated enough monster thrills to be licensed to Paramount Pictures for a major release. The sharp businessman Harris then made a deal with Universal, and he and Yeaworth immediately turned out a more sophisticated science fiction item about a man who can walk through walls, 4D Man (1959). Producer Harris wisely retained the rights for both of these pictures.

Irvin "Shorty" Yeaworth originally partnered with Harris only to generate money for his religious film company, and had to be talked into teaming a third time on this more juvenile monster movie. The Valley Forge facilities were impractical for filming Harris's story about revived dinosaurs creating chaos in the tropics. Universal okayed a brief shoot in the Virgin Islands, followed by a short shooting schedule back in Hollywood.

In interviews with Tom Weaver, Jack H. Harris claimed that he consulted with the celebrated science fiction author Alfred Bester to cook up a semi-plausible rationale for the unlikely resurrection of reptiles dead for thirty million years. The prize for cleverness in that field would be won years later when Michael Crichton worked out a brilliant, almost feasible method for growing extinct animals from preserved DNA. When struck by a bolt of lightning, the frozen monsters of Dinosaurus! simply roar and walk away, as if leaving a charging station for all-electric vehicles. Although Harris also stated that he tapped another noted sci-fi author, Algis Budrys, to sketch out the film's characters and plotline, neither author is credited on the film. Top writing talent was hardly required to come up with Bart's put-down of Hacker: "I wouldn't trust him as far as I could throw a... a dinosaur!"

The screenplay for Dinosaurus! is an undemanding assemblage of off-the-shelf relationships and stereotypes. Bart's main sidekick is a jolly, portly fellow with the demeaning name "Dumpy" (Wayne C. Treadway), and a construction guard is an Irish alcoholic named O'Leary (James Logan). Second-string hero Chuck (Paul Lukather) has a soft spot for Hacker's barmaid Chica, who must put up with dialogue lines like, "You're my little tamale, aren't you?" Harris said that the credited co-screenwriter Jean Yeaworth, Irvin's wife, contributed the film's slapstick comedy involving the Neanderthal investigating a modern house.

With the exception of the caveman scenes, most of the movie is played straight. Little Julio is an identification figure for small children. He is shown playing with his own dinosaur toys -- which the Bluto-like villain Hacker stomps into the ground. Hacker's style is so off-putting that his own lackeys soon desert him. Director Yeaworth claimed that Dinosaurus! was filmed with a tongue-in-cheek attitude, to appeal to kids and adults alike. Most of what happens in the movie is absurd but the only developed bit of self-parody occurs when the black-hearted Hacker uses a broken bottle to threaten the hero. Instead of breaking as bottles seem to do in every western and juvenile delinquent film ever made, this bottle just shatters and gives Hacker a nasty cut. It's hilarious, like a "Scene We'd Like to See" from the old Mad magazine.

The production began filming on St. Croix in the Virgin Islands for key shots of Bart's dredging project and the many background plates to be rear-projected back in Hollywood. The film's attractive, colorful look is the work of ace cinematographer Stanley Cortez, the talent behind such arrestingly-filmed classics as The Magnificent Ambersons [1942], Since You Went Away [1944] and The Night of the Hunter [1955].

Casting had been a strong suit for Harris and Yeaworth on their first two pictures, as their relative proximity to the New York stage netted strong actors, several of whom went on to prominent careers. After their stroke of fortune in hiring Steve McQueen, 4D Man's cast included newcomers Robert Lansing and Lee Meriwether. Able support in the first two pictures included James Congdon, Robert Strauss, Aneta Corsaut, Olin Howland and even a young Patty Duke. Unfortunately Dinosaurus! was cast with talent that may have been drawn from the studio's contract list.

Back in Hollywood Yeaworth and Harris filmed on stage interiors that include a fairly lush interior jungle setting. The special effects were also underway at Projects Unlimited, a small but energetic outfit known for work on films like George Pal's The Time Machine [1960] and the TV series The Outer Limits. Some shots were accomplished with model dinosaurs manipulated like hand puppets but the bulk of the monster footage is old-fashioned stop-motion animation. The quality of the animation varies greatly, and never approaches the artfulness of master animators Ray Harryhausen or Pete Peterson. The dinosaur models were built by Marcel Delgado, the craftsman who worked with the legendary Willis O'Brien on classics like Kong and Mighty Joe Young [1949]. As opposed to Delgado's expected fine work, these animation puppets are unexpectedly crude, with skin textures that look too much like wrinkled foam rubber. Author Bill Warren reports that the metal armature 'skeletons' for the saurian stars of Dinosaurus! ended up in the collection of Forrest J. Ackerman, where it could be seen that they were partially made of wire, a definite hindrance to good animation work.

The animation of Dinosaurus! may be weak, but every dinosaur scene has something creative going on. The Tyrannosaur smashes a bus and tries to dig its way into a cave. The Brontosaurus gives the Neanderthal and Julio a spirited ride, alley oop-style, before becoming mired in quicksand. The Universal sound department mixes Ronald Stein's active music score with plenty of prehistoric growls, screams and bellowing, which adds greatly to their effectiveness. Spread across a large screen, the noisy spectacle entertained a lot of children. Julio's enthusiastic assessment of the Brontosaur: "Boy he's magnifico, that's for certain!" Considering that the boy already has toys of the two dinosaur characters, we wonder if the writers ever considered making the bulk of Dinosaurus! into a Wizard of Oz- (1939) like dream experienced by the young Julio.

The great Willis O'Brien is also not credited, but producer Harris told interviewer Tom Weaver that he discussed effects techniques with the famous expert, who dispensed plenty of good advice. O'Brien may have contributed more to Dinosaurus! than he realized. The Tyrannosaurus Rex is finally dispatched by a steam shovel, an ending similar to the concluding scene of O'Brien's unrealized RKO project Gwangi, in which a dinosaur is knocked off a cliff by a truck. When Ray Harryhausen finally filmed O'Brien's story as The Valley of Gwangi (1969), he had to relocate his final scenes to a burning cathedral.

The hit of the show turned out to be not the dinosaurs but Gregg Martell's amusing turn as the confused Neanderthal. Kids weren't concerned by the fact that dinosaurs and primitive man never co-existed, and instead went crazy over the hairy, wild-eyed cave man's tour of Betty's house. The hungry fellow is frustrated when he tries to eat some decorative wax fruit, and his antics in front of a full-length mirror are clearly modeled after scenes from The Marx Brothers and Charlie Chaplin. Martell's expressive mime and slapstick timing got big laughs when the Neanderthal flushes a toilet, and runs in terror after coming face to face with Betty's mother, wearing curlers and covered in face cream. The screenplay also takes a welcome step by having the Neanderthal heroically rescue Betty from the rampaging Tyrannosaurus -- and then claiming Betty as his mate!

The New York Times review was quick to demean Dinosaurus! as "a tired, synthetic, plodding sample of movie junk." Although given a cold shoulder by the critical establishment, the film became a reasonable hit. Irvin S. Yeaworth continued his film work, eventually becoming a concert promoter and creator/consultant for amusement parks. He was working on a Jordanian attraction when he lost his life in a car accident in 2004. Jack H. Harris continued to roll the dice with young filmmakers, adapting a 16mm film by future special effects director Dennis Muren into the 1970 release Equinox, releasing John Landis' homemade monster spoof Schlock in 1973 and helping young John Carpenter turn his student film Dark Star into a theatrical release (1974). His most prestigious later credit was as executive producer on Irvin Kershner's Eyes of Laura Mars (1978) starring Faye Dunaway, from a script by Carpenter. Always one to see an income opportunity, Harris sold a single B&W shot of his Brontosaurus for an episode of TV's The Twilight Zone. Later on, his dinosaurs turned up as stock footage in several episodes of the caveman series It's About Time. Harris made sure that he was duly credited in both instances.

Dinosaurus! remains a holdover from the 1950s, a juvenile monster adventure with a strong streak of comedy and an aversion to intense jeopardy or gory details. Young Julio identifies the two beasts as a "good" vegetarian and a "bad" carnivore, and sure enough, the dinosaurs prove the boy's scientific approach to morality to be completely correct. And the film's slapstick Neanderthal is a childhood favorite. Not every dinosaur fantasy can be Jurassic Park (1993), and Harris and Yeaworth's amusing kiddie show has earned its modest place in monsterdom.
