Home Alone is the only movie I've ever seen in theatres twice. I absolutely love it and watching it always reminds me (as I am sure it does many) of the Christmases of my childhood. If you love that movie as much as I do and have $2.4 million USD, you can live on the set of the movie (circa 2011-style) permanently.
The house is for sale in a suburb just outside Chicago! Via Cup of Jo. Photos of the movie set and how those same rooms look now via AOL.
