EXCLUSIVE: George Takei Warps to 'Big Bang Theory'

This season, only one of the quartet will share a scene with 'Star Trek's' Sulu, George Takei, who'll play himself on the CBS comedy in an episode tentatively scheduled for Thu., Oct. 14.

In that episode, Takei will appear alongside fellow geek icon Katee Sackhoff ('Battlestar Galactica').

In an interview, Prady explained that Wolowitz is thinking about getting back together with his ex-girlfriend Bernadette (Melissa Rauch), and it sounds as though Sackhoff and Takei will represent opposing points of view.

"George Takei plays himself, and he's the other person guiding Wolowitz in his thoughts as he tries to figure out what to do about Bernadette," Prady said.
