Breaking Bad star Bryan Cranston mooned his longtime castmate Aaron Paul to cheer him up during their final scene on the hit TV drama. Paul admits he was struggling to come to terms with the end of the longrunning show as the cast and crew were gathered for the final day of filming earlier this summer (13) and his pal found a way to make him smile - by baring his butt. He explains, "When he (Cranston's character Walter White) cooks (meth), he cooks in his tidy whities (underwear) in the winnebago, and the final set up is my coverage (of my face) and he's in an apron in his underwear and the final take, he comes walking up and the camera can just see his backside, I can't. "I just hear outside people laughing and I'm trying to hold in my tears because I know the show's almost done, and then he just turns around and starts walking away - and he's naked. He had just pulled down his pants." Paul hopes to alleviate the sadness of the final episode by watching it with hundreds of fans at the Hollywood Forever Cemetery in Los Angeles on 29 September (13). He adds, "I rented out the Hollywood Forever Cemetery, where we're gonna play the pilot episode and the final episode the night it airs... It sold out within, like, 60 seconds and all the proceeds are going to my wife's charity, Kind Campaign." And he has a real treat for one lucky fan as part of a competition to win tickets for the Breaking Bad screening: "The grand prize is a trip for two to Los Angeles, I will pick them up at the airport, we're gonna go out for dinner and then hopefully toilet paper Bryan Cranston's house and then we're gonna meet up with Cranston and get into the winnebago, put on some Hazmat suits and drive to the cemetery together and meet up with the entire cast and the creators and writers and watch the finale together."
