Nalder appeared (at the request of star Frank Sinatra) in a brief, uncredited role as a communist spymaster in John Frankenheimer's 1962 film The Manchurian Candidate. He also had a brief role in the 1981 Walt Disney film The Devil and Max Devlin. In an interview, Nalder claimed that he could not stand working with Bill Cosby, the star of the film. He described him as "a pig", as well as "rude, arrogant, and very untalented."
