"The Big Bang Theory" will celebrate its 200th episode with several famous faces, including Batman himself, Adam West. West, 87, who played Batman in the 1960s TV series, will be appearing on the hit CBS sitcom for the first time and will play himself in the milestone episode, according to Us Weekly. He will also be joined by returning favorites Sara Gilbert as Leslie; Christine Baranski as Leonard's Mom Beverly; John Ross Bowie as Barry; and Wil Wheaton as himself.
Baranski, Bowie and Wheaton have all made several appearances in recent seasons, but Gilbert's character hasn't appeared since the Season 3 finale. She and Leonard (Johnny Galecki) dated at one point, and the last time she was seen, he was trying to rekindle the flame.
West has only made minor TV appearances as himself in the past few years on series like "30 Rock," "King of Queens," and "NewsRadio," but has done a lot of voiceover work, according to Digital Trends. Because of his distinctive voice, he's played himself on several episodes of animated series like "The Simpsons," "Futurama," "Rugrats," and he continues to play the recurring role as the voice of Mayor Adam West on "Family Guy."
The 200th episode is set to air on Thursday, Feb. 25 at 8 p.m. on CBS.
