James Garner made a lot of great television and some very good movies. So is it wrong that my favorite memory of him was for a series of commercials that he made for Polaroid beginning in the late 1970's? If so, I don't care. They were a lot of fun.
My favorite James Garner movie was The Thrill of it All, with Doris Day. It is also my favorite Doris day comedy. Carl Reiner was one of the writers and it was hilarious. Unfortunately there are no really good clips from it on Youtube so you'll just have to go rent it.
