It seems I have a lot of absolute favorite movies, but this is definitely one of them. Stranger Than Fiction is just such a special story and it has the perfect balance between being funny and somewhat heartbreaking.
Now I know Will Ferrell isn't everyone's cup of tea. He's done some bad movies, but he's done some amazing ones too. This one possibly being his best. And he is backed by an incredile cast of actors: Emma Thompson, Dustin Hoffman, Maggie Gyllenhaal, Queen Latifa and they also persuaded Tom Hulce, who hadn't really done much since Amadeus.
If you have access to a dvd with extras I suggest you watch them. It has some lovely interviews as well as some original deleted scenes(as I know those are often pretty boring).
If you know of any similar movies, let me know in the comments, I'd love to hear about them!
