It's not hard to say goodbye, I've had 60 years of working in films and television, and I'm very grateful for the opportunities I've had. I had decided not to do any more acting and directing several years ago, but I was called back to do the Star Trek movie. And then J.J. Abrams asked me to play the William Bell character, and I thought I owed him that — and I'm very glad I did it, he's an exciting character — but I had decided long ago that I just didn't want to do this anymore. I did this last job as a favor to J.J. Abrams and I'm glad I did it.
