A three-way race for best actor?

On his Gold Derby blog, the L.A. Times' Tom O'Neil posits that it could be a three-horse race for best actor, with Leonardo DiCaprio attracting votes for his work in The Departed even though he's nominated for Blood Diamond. There's already been a lot of buzz that Peter O'Toole could upset Forest Whitaker, but I'm sticking with Last King of Scotland star Whitaker as my pick.
