A 10 minute clip of the Judd Apatow documentary is on youtube. It focuses on him and Rickles. Funny stuff, although be warned Newhart looks very frail in it. Newhart and Rickles and the wives were going out to dinner. Sinatra wanted to come but they just wanted the 4. Newhart said "did you ever think we would get to the point where we are turning Frank Sinatra down for dinner?"
