Richardson, a Simpsons regular, was recently announced as taking over the Dr. Hibbert role from Harry Shearer. But in a BBC News interview, he admitted that he turned down the job last year. "I was very fortunate to be asked to play the role, which, I must say, about a year ago, I declined," Richardson said. “But I was asked again and I just said yes, but I had no idea the impact it would have on the fans, and so many viewers. So I just want to have fun with it. And play around with it. And just hopefully evolve into that jolly socket that Mr. Shearer had created."
