Why Christopher Lloyd won't retire

"I don't really mind as long as I'm working. Whether it's a lead or cameos, or supporting roles, I love to be doing it. I don't wait around for the ideal role to come my way -- I'll take what's given," he said, reports contactmusic.com.

In an interview with The Guardian, he said that acting helps him express himself.

"I need to express myself. And I gradually discover that through acting in a role, I could relate to people. So, I stuck with it," he said.

In fact, the 82-year-old actor enjoys playing his age on screen.

"I enjoy playing characters of the age I have now. I mean, they're just as interesting as younger characters," he said.
