Christopher Lloyd is set to guest star in 'Big Bang Theory'

“Back To The Future” star Christopher Lloyd is set to guest star in “The Big Bang Theory” this December.

Lloyd, 78, who played the iconic role of Emmett ‘Doc’ Brown in all three “Back To The Future” movies between 1985 and 1990, is to star in the December 1^st episode of “The Big Bang Theory”.

Details about the role he is set to play are being kept under wraps for the time being, but his appearance is in keeping with the show’s tradition of bringing in guests from other sci-fi-related films and TV shows, reported Variety.

Created by Chuck Lorre and Bill Prady and run by Steve Molaro, “The Big Bang Theory” is currently in the middle of its tenth season.

“We’re so excited to be working with Christopher Lloyd, and think we’ve created a fun part that fans will really enjoy,” the CBS show’s producers said in joint statement.

Comedic legend Lloyd, who won three Emmys for his role in “Taxi” in the 1970s and who made his film debut in the critically-acclaimed “One Flew Over the Cuckoo’s Nest”, was last month tapped to guest-star in Syfy’s new time-travel drama “12 Monkeys”, an adaptation of Terry Gilliam’s movie of the same name.
