Did you know that Leonardo DiCaprio was the original choice for Landa?

Yes, but only because I read up on the film immediately after seeing it, as is my custom. I like DiCaprio, but the role was wrong for him, I think. I can only imagine his Landa as being like INTENSE... BROODING... STERN... INTENSE... BROODING. Part of what I loved about Waltz's performance was that he showed the character having fun with his job-- you can see why he does what he does the way he does it: because that's the way he does it best, because that's the way that's the most fun for him.

In fact, I wasn't too sure what to make of IB because of its advertising campaign

I'm not sure why I wanted to see it so badly; the trailers made it look like ACTION ACTION ACTION BRAD PITT ACTION HUMOR ACTION. In short, like a Guy Ritchie movie.

But if you feel the need to read fic wherein Landa rapes Shosanna and plows Hellstrom, then you're in luck.

Eeuh. Absolutely the fuck not. I'm still a bit upset about all the things that happened to Shosanna in the film; there's no way I want to read about yet more tragedy being heaped upon her.
