While we were sleeping, everyone decided that we were calling Tr2n Tron 2.0 again, so while we sort that out, we thought we’d bring you some fantastic casting news for those of you who fancy hot women in your science fiction sequels.

Joseph Kosinski, the director at the helm for the Tron sequel has lined up his first cast members, and they are…

B&U favorite Olivia Wilde (House) and Beau Garrett (Entourage, Rise of the Silver Surfer), who is pretty good, we guess. We got a flash of her boobs in Turistas, so that’s mostly what we remember of her. Wilde will play a worker in the virtual world who tries to help fight Master Control Program, the villainous intelligence protocol that was the nemesis in the original film. Garrett will play a siren in the virtual world.

And according to the Hollywood Reporter, Wilde ("Thirteen" in Fox's medical drama, although she'll always be Seth Cohen's girlfriend Alex to me) will play "a worker in the virtual world who tries to help fight Master Control Program, the villainous intelligence protocol that was the nemesis in the original film," while 4: Rise Of The Silver Surfer's Beau Garrett has also signed up for the movie, and will play the (as-yet uncast) male lead's cybernetic love interest inside the computer world.

Last we heard from Tron 2.0, we expected to see it as a 3-D feature in late 2010 (and it was called Tr2n).
