Big Bang Theory 200th

Big Bang Theory 200th Ep Welcomes Adam West, Sara Gilbert, 3 More

It all started with a big KAPOW!

The Big Bang Theory has unveiled the guest list for its 200th episode (airing Feb. 25), and it includes a first-ever appearance by Batman icon Adam West, TVLine has learned.

Also set to guest star in the milestone outing are recurring Big Bang players Christine Baranski (Beverly), John Ross Bowie (Barry), Wil Wheaton (as himself) and Sara Gilbert (Leslie).

While Baranski, Bowie and Wheaton have all been steady fixtures on the CBS smash in recent seasons, Gilbert’s physicist character hasn’t been seen since the Season 3 finale, when Leonard showed up at his ex’s door looking for a quickie in the wake of his split from Penny.
