In the opening credits, after the initial three explicitly credited star names, it reads: "and A GALAXY of STARS".
Cast members listed following Billy Benedict are identified by the narrator or other cast members. Those following Truman Bradley are identified by him as he announces a celebrity baseball game. Of the three Ritz Brothers, only Harry Ritz is identified individually; Al Ritz and Jimmy Ritz are later identified collectively as 'The Ritz Brothers'.
Except for the tourists and tour guide, all cast credits are given orally during the movie.
