But nobody "makes" Jim Carrey do all that rubber-faced idiot bollocks - it's what he does naturally. In the one or two decent performances he's done I bet they had to force him to stop gurning and behaving like a cretin.
I always assumed that was what he was paid for, and he probably assumes the same, which might be why he has so many films playing the same stage persona he built up over his standup career.
He is, however, consistent and only seems to fall down due to poor direction or scripting in a lot of the films he does.
I was figuring he could use that persona and another one to create a really creepy nutter version of the character.
As it was, in Batman Forever, he just did what he usually does as it gets the money in.
I thought Robin Williams would do well as he's a bit older and so it could be implied he was active before the events of the first film in the series (an innocent man being sent to Arkham asylum) and is mistaken for a copycat killer.
This would allow them to use Arkham as a location as well as remove the campiness from the character without completely re-writing him.
