Walter Matthau is at his most likable and the movie has an amiable shaggy-dog-story vibe. And then in literally the LAST SCENE, Matthau does brownface as a Sikh for no good reason and I had to think, "Hey, read the room, movie from 1980!"
TCM's print was fairly soft looking--does the Criterion Blu-ray look this unimpressive?--and the color scheme tends toward browns and, for variety, off-browns. Man, that era could get pretty ugly. (Don't get me started on the wallpaper!)
