There is now photographic proof that the wheels are turning on the fourth season of Lost.

On the ground is Ken Leung, who, as we reported last month, is playing “a brilliant mathematician who is capable of great insights and has a tremendous knowledge across various scientific fields”.  Apparently he’s one of those gun-toting, parachuting mathematicians.  My bet is that he is one of the boat people alluded to in the finale last season.

Oh, and I see London, I see France…I see Jack’s underpants.
