My pony rarely wins, but I am somewhat perplexed at no lead acting Academy Award nominations for 'Atonement'. James McAvoy is a brilliant actor and was stunning as Robbie in the film. If you haven't seen it, get to it, you won't be disappointed. See the trailer and some teasers here. I'll have to get my fix via the British film awards.
The book by Ian McEwan is amazing as well. I read it before I saw the film and kept wondering how the movie experience would have been different if I didn't know the ending. It's one of my favorite reads of all time and I'm certain people are tiring of me raving about it and begging them to read it.
