The hit CBS comedy "The Big Bang Theory" will celebrate its 200th episode in a big way -- with a guest appearance by iconic Batman actor Adam West.
He'll be joined in his first appearance on the series by such familiar faces as John Ross Bowie, Christine Baranski, Sara Gilbert and Wil Wheaton. No plot details have been revealed.
"The Big Bang Theory" has featured a long list of memorable guest stars over the past nine seasons, from Carrie Fisher and George Takei to Stephen Hawking and Stan Lee to James Earl Jones and Leonard Nimony (in a voice role).
The 87-year-old West, who so memorably played the Caped Crusader on the 1966 "Batman" TV series, has largely stuck with voice work in recent years, most notably in his recurring role on Fox's "Family Guy."
The 200th episode of "The Big Bang Theory" will air Thursday, Feb. 25, on CBS.
