While the story follows Buddy Holly from age 19 to 22 (1956 to February 1959), Busey was 33 when he played the role. Charles Martin Smith auditioned for the role of Buddy, but since Busey already had been cast, the producers cast Martin to play Ray Bob Simmons because they liked his audition. Simmons and Jesse Charles were character names used in place of Joe B. Mauldin and J.I. Allison, two of the actual Crickets (1956 to early 1958 Cricket Niki Sullivan, performing on 27 of the 32 songs Holly recorded, is not shown).
