One thing to keep in mind about Sean is that he is Famous Hollywood Offspring. His mother won an Oscar. The Academy votes for the story behind the actor as much (if not more) than the actual performance. Hence Gwyneth Paltrow's win, Laura Dern's nomination, everything Michael Douglas ever did, and Sofia Coppola's guaranteed nomination. If the Academy looks at Sean in terms of second generation Oscar winner, and what a fantastic acceptance speech he'll make mentioning his mum, his chances of getting nominated are greater. At least that's what I'm desperately clinging to.
