When you take on a new job as an actor, one of the things that probably doesn't go through your mind is, "what if this is my last film?" But perhaps it should be. Here, I present a list of some actors who deserved better as cap on their careers (I'm not counting post-mortem re-use of someone's likeness or archival footage).
DeForest Kelley - The Brave Little Toaster Goes to Mars
Orson Welles - The Transformers: The Movie (though he played a bit part in another film after)
Scatman Crothers - The Transformers: The Movie (had a narrator role after)
Raul Julia - Street Fighter
James Doohan - The Duke
Milton Berle - Storybook (though he was on TV quite a bit, after)
Jonathan Winters - Cattle Call (Winters had been in some unfortunate films, but this is just sad)
I'd like to think that I'm doing all of these actors a service. To a last one, I think they deserve to be remembered, and who knows... perhaps their unfortunate final projects will ensure that.
