Although the opening credits indicate that Vanguard Productions copyrighted the film in 1956, it is not included in the Copyright Catalog. The title card of the viewed print reads Rock Rock Rock!, without commas. However, all available contemporary sources, including the pressbook, list the title as Rock, Rock, Rock!. Photos of the cast appeared under their names in the opening screen credits. Bert Conway, who typically worked as a casting director, was credited onscreen as dialogue director and a cast member, but was listed in the pressbook as casting director. Monroe J. Sachson, whose name does not appear in the pressbook, was credited onscreen as the casting director. The music group the Three Chuckles is credited onscreen as "Teddy Randazzo of the Three Chuckles."
The pressbook and some contemporary news items indicate that there were twenty-one songs in the film, but the viewed print contains only twenty songs. The Motion Picture Herald Prod Digest review also reported twenty songs. In a synopsis in the pressbook, Tuesday Weld's character is called "Dori Grey," however, her surname in the film is Graham. An unidentified contemporary news item reproduced on a website dedicated to Alan Freed noted that the performers lip-synched to their own recordings in the film. An August 1956 Hollywood Reporter news item noted that Rock Rock Rock! was shot over a period of two weeks at Mikaro Studios in Bronx, NY, and that the production was budgeted at $80,000. A December 1956 news item in Cue noted that the total production cost was $125,000.
Rock Rock Rock! marked the feature film debuts of Connie Francis, Tuesday Weld and Valerie Harper. Connie Francis does not appear onscreen, but she was given screen credit for dubbing Tuesday Weld's singing voice. Although Weld acted in The Wrong Man (see below) before Rock Rock Rock!, The Wrong Man was released after Rock Rock Rock!. Modern sources add that singer Bo Diddley appeared in the film, and that some scenes were shot on location at The New York Botanical Garden.
