Studios sent screeners of Half Nelson out to Academy voters this week. Ryan Gosling is an outside shot for a nomination. His performance is outstanding.
Little Miss Sunshine has been in the Academy's hands for a few weeks now and will arrive on DVD for the general public in December.
World Trade Center and United 93 are also out there. Tom O'Neil of the L.A. Times says United 93 is everywhere in Hollywood.
This is a smart strategy. With Flags of Our Fathers struggling at the box office, studios need to capture on the opening. Keep and eye out for United 93 and Little Miss Sunshine. One of these films may surprise and take that 5th nomination spot, which I think is now up for grabs.
