'Sherlock' is 'Elementary' for Lucy Liu

Lucy stars as Dr. Watson to Johnny Lee Miller’s Holmes. The two say it's all about keeping things light and funny on set.

“He knows a million jokes and he remembers all of them -- and he can pull them out of his hat at any minute, which I love,” she explained. “I can’t remember any. And I always think, ‘Oh, my God, I have to remember that,’ and I never do. I never remember the punchlines.”

Miller added, “If you’re going to spend a lot of time with someone, you really need to be able to get on with them. It’s nice because we have a very similar sense of humor. Still, you usually have to explain jokes to her about three or four times.”

The cast is now more like a family, Liu said. “It’s nice to know that you can enjoy the company because I don’t think that’s always the case.”
