Movies for the day: TWoO

Rico says he and the fiancée started to watch The Wizard of Oz, but gave up before they got to the Emerald City (photo). There's an actor crossover between it and It's a Wonderful Life:, but Rico hasn't yet found it.
Rico's fiancée pointed out that Judy Garland's daughter, Lorna Luft, married the son of the Tin Man, Jack Haley. Lorna is Garland's daughter by her third husband, Sid Luft, with whom she also had a son, Joseph.
