Fantasy Casting Couch

Hi all, tim r here, guesting from mainlymovies. This is following up on a suggestion down there in the comments somewhere: parts you've always wanted your favourite actors/actresses to play. Nat's dream is for Toni Collette to do a biopic of Liza Minnelli. My dream is to see Peter Sarsgaard do Iago, or failing that, for Annette Bening to play Liza's mum. See below for the obvious sense this all makes. Now let's have some of yours!
