It looks like Ausiello Files got wind of a new casting call out for Lost. According to his Lost insider, the team is looking very quietly for an actor to play a "younger Phillip Seymour Hoffman-type" for a small episode arc this season and an even bigger on next season.
As EW's resident Lost exprter, Doc Jensen puts it, "My guess is they want the Phillip Seymour Hoffman from Synecdoche, New York, because thematically, that trippy movie is very simpatico with Lost. I'm thinking he's some kind of Dharma mastermind, or maybe Jacob -- the true man behind the curtain directing the crazy stage play that is Lost."
Oh and as a bonus spoiler, it looks like Sawyer and a female cast member that is not Kate will be making out this season. Go Sawyer!
