Miscasting--you know it's really bothering me!

I watched Billy Wilder's Love in the Afternoon last week. I'm a huge Wilder fan, but I think he sometimes had problems with his casting. I adored this film, I really did, but I couldn't fully get behind Gary Cooper as a romantic lead.

So this made me start thinking about other films I like with miscast roles (Like Bogie in Wilder's Sabrina).  Or films I don't like because of the miscasting (don't hate me, but Tippi Hedren in Marnie).



Thoughts? Any films/roles you think are miscast?
