Bill Murray
Bill Murray got his start on Saturday Night Live many years before playing Garfield the cat in Garfield: The Movie, and like several of the other actors and comedians on this list, he began his career on the show. Aside from lending his voice to Garfield, Murray is a prominent actor who has been awarded an Emmy and a Golden Globe.
Not only that, but Bill Murray has acted in numerous films, including Hyde Park on Hudson, Groundhog Day, Lost in Translation, and Ghostbusters. He served as a co-director for the 1990 film Quick Change. Murray is an excellent actor to call on if a film requires deadpan humor.
