OK, so they don’t really have anything to do with each other; but as I watched this, the idea become more and more deeply seated in my mind that this was somehow a prequel, of sorts, where Macaulay Culkin’s time spent with uncle Buck is what enables him to be able to do the things that he does in Home Alone (1990).
Huh. Well, apparently, “The concept for this movie (Home Alone) originated during the filming of a scene in Uncle Buck (1989), in which Macaulay Culkin plays a character who interrogates a would-be sitter through the letter opening in the front door.” So there is a real connection, at least, even if my own personal head-canon isn’t firing with a full charge of powder.
