"Who is Cletis Tout" is a noirish little crime comedy romp which tells of a movie quoting film fan and hitman (Allen) who holds an excon and flimflam man (Slater) at gun point while the latter recounts why he isn't who the former thinks he is via flashbacks until the flashbacks catch up with present time and the film runs out from there. Got that? If it sounds a bit convoluted, it's because it is. However, there's enough good natured, not-to-be-taken-seriously fun going on in this busy flick to make it marginally enjoyable even if you don't try to follow the story and just no-brain it. A happy mix of murder and diamonds and love and chicanery and groaners, etc. which will make for a lukewarm critic frustrating couch potato watch. (B-)
