You're out of the club.

I was only joking about that whole sarcasm tag thing. As dorkman pointed out, my idea was really dumb.

Totally cool of you to implement that, tho, Holden. You are awesome.

Why WAS old Weyland played by Guy Pearce in make-up? Surely it wasn't just so they could do that TED Talk thing as part of the viral marketing...

Oh, and as for why Weyland is played by Guy Pearce in old-man makeup, Spaihts says Damon Lindelof's script showed the android David going inside Weyland's dreams while he was in hypersleep — and in his dreams, Weyland is a young man, on a yacht surrounded by beautiful women. These dream conversations got cut, but Pearce's casting was already locked in. Scott had originally wanted to cast Max von Sydow as Peter Weyland. (In Spaiht's script versions, Weyland isn't aboard the Prometheus at all — instead, there's a hidden squad of company soldiers.)
