You can sit in Sheldon’s spot!! THE BIG BANG THEORY’S sets are now a part of the Warner Bros. Studio Tour. Guests can see the original sets for apartment 4A, the CalTech physics lab cafeteria and the infamous broken elevator. Costumes worn by Sheldon (Jim Parsons), Leonard (Johnny Galecki), Penny (Kaley Cuoco) and the larger cast will also be on display. “For 12 seasons and 279 episodes, the cast and crew of The Big Bang Theory found their home away from home on these sets on Stage 25,” said co-creator and executive producer Chuck Lorre in a statement. “We’re thrilled that Apartment 4A and other Big Bang locales will remind visitors of all the laughter that took place on our show.”
