At a typical Oscar party, everyone pays lots of attention to categories like Best Picture and Best Director. But for folks "in the business," categories like Sound Mixing or Costume Design can matter just as much. 

Producer Fabienne Toback has been attending and sometimes hosting an Oscar viewing party with her industry friends for years. Because all the party-goers have some insider knowledge, Toback says their friendly Oscar pool can get pretty competitive. 

Everyone has to fill out their ballots ahead of time to make sure no one cheats by texting with a friend who's attending the awards show, and no one scores their own ballot.

Toback and her friends take things so seriously, that she says friends who are working on set and out of town have been known to mail their ballot ahead of time and Skype into the party.

But it's still all in good-natured fun, Toback says. "There are times where there's a friend who is nominated, and I can't help it, I vote for them because I feel like that's good juju. Even if it means losing the Oscar pool."
