- Dick Van Dyke and Paul Lynde, both veterans of the 1960 Broadway hit, were displeased with the film version.
- The title tune which opens and closes the film was written for the screen version, and was not from the Tony-winning Broadway musical.
- Ann-Margret's skirt-flipping/hair-tossing rendition of the song was filmed six months after principal photography was completed, at a cost of $60,000.
- The sheet music of Birdie's next hit song, "Mumbo Jumbo Gooey Gumbo", which Albert picks up from the piano in his first scene, is the same music as the title tune, "Bye Bye Birdie."
- The song that made Dick Van Dyke's career, "Put on a Happy Face" was unsuccessful in early showings of the musical and almost cut from the production.
- Albert's music company is called "ALMAELOU." This is an amalgam of his name, his mother's name, and his late father's name.
