While true Lost spoilers are still difficult to come by, show producers have released a casting notice that sheds a surprising amount of light on a new character.
For season six, the show is seeking an actor in his mid 30s to late 50s to play someone named "Lennon." Here's how he's described:
Scruffy, edgy, charismatic, and slightly stir-crazy, Lennon can be deferential when it’s called for. He’s the spokesperson/translator for the president of a foreign corporation. He’s a wily negotiator, and far more powerful than his lowly position would seem to indicate. Recurring.
A foreign corporation? Could that be the Hanso Foundation? Send in your theories as to how this new character fits into the Lost puzzle.
