His other Broadway credits included "One Flew Over the Cuckoo's Nest" (1963, with Kirk Douglas), "The White House" (1964, with Helen Hayes) and "Luv" (1966), but it was a 1963 Broadway production of "Mother Courage and Her Children" that altered the course of his life forever. In its cast was Anne Bancroft, who was dating Mel Brooks at the time, and the relationship established between the two men eventually led to Wilder's becoming part of Brooks' "stock company".
