We have an update on Summer Glau's guest appearance on The Big Bang Theory.  As we already know from reported spoilers, Summer Glau will appear as herself on a train the boys are riding to San Francisco to hear Dr. Smoot (playing himself!) giving the keynote address.

Now thanks to the latest Ausiello Files, executive producer Bill Prady tells us, "For the guys, there’s probably no more awesome sci-fi female to encounter than Summer Glau, with her nerd-cred times four. Normally, these guys might only have a split-second autograph encounter with her at Comic-Con, but now they have 11 hours to get up the courage to talk to her -- and she’s sitting alone!"

Oh and he also gives us an amazing Sheldon quote from the episode: "If Terminators actually did exist, a perfect way they could lull victims into a false sense of security would be to pose as actors who have played Terminators."

The episode airs on March 9th so get your TiVo ready.
