...for Best Film Performance by an Actor Channeling Cadillac from Planet Unicorn goes to:
Diego Luna in Milk!*
My full thoughts on Milk will probably be doled out sometime during the Oscar crush, as I fully expect it to show up large in the race.
*Not to say I hated the performance or anything, it's just that there were times that the vocal resemblance was uncanny! And you know it just made me long for a cameo from Feathers.
