Who says history doesn't repeat itself? Cinescape's asticle on an animated feature called Big Bug Man mentions that

BIG BUG MAN will also feature the voice of Marlon Brando, the legendary screen actor that recently passed away. Brando recorded a supporting part for the film before his death last week.

Those of us who are From The 80s will, of course, recall that Orson Welles' final film role was as the voice of Unicron in Transformers: The Movie.
