I had an offshoot idea that may be worthy of its own thread. But there may not be nearly enough cases of this. Same actor, Different character only in name. Where an actor is basically playing a very similar role to one they have played in another film.
Funny, I had that idea myself. But I think you should post it, as I'm too lazy. I have a couple of suggestions for the thread if you do, though.
I can think of plenty of examples, too.
