The Big Bang Theory - Casting News

Thanks to SortofBeautiful for the heads up.

This has been a big week for The Big Bang Theory's nerd herd. First, they score their best ratings ever, and now they're getting to rub elbows with frakkin' Summer Glau!

The Sarah Connor Chronicles siren will play herself in the March 9 episode, the set-up of which already has me ROFWLing: A train trip to San Francisco takes a major detour when Leonard, Sheldon, Wolowitz, and Raj discover that their favorite sci-fi actress in all the land is on board. But the fanboy frenzy quickly gives way to a heated mass debate (tee-hee) when they realize one of them will have to approach her -- but who?

It's not too difficult to figure out how this cheeky cross-over came about, provided you know this little detail: The Big Bang Theory and Sarah Connor Chronicles (which returns this Friday) are both produced by Warner Bros.

This is what we in the TV biz refer to as extremely positive synergy.
