The same year he also appeared as Barlow in the John Milius surf film Big Wednesday opposite Jan-Michael Vincent and Gary Busey.

Katt auditioned for the part of Luke Skywalker in 1977's Star Wars, and footage of his audition has been featured in many Star Wars documentaries. The role went to Mark Hamill, and Katt instead starred that year in First Love.

!In 1981, Katt was cast as the title role in a filmed version of the Broadway musical comedy Pippin, which film received mixed reviews.
