There are 4 Home Alones over all, the 3rd with a new kid and the 4th was a TV Movie.

Heard about the forth one. I think it's hilarious how they had that guy from Third Rock from the Sun play Harry [the smart one], and it is unmistakably him with the hat, the clothes and the mannerisms. Yet they've named him Marv, which was the stupid one's name. As if!
