Tom Cruise..golden globe? Are you kidding me?

Does anyone know why Tom Cruise was nominated for a 5 minute cameo for some crappy movie? To be a supporting actor, shouldn't you have a bigger role in the movie than that? How is it that the Dark Knight got the same amount of nominations as Pineapple express? Instead of nominating Tom Cruise, they could have nominated Aaron Eckhart, Morgan Freeman, or Michael Caine for best supporting actor alongside Heath Ledger. What are you opinions of the nominations?
