Home Alone - I still laugh my ass off when Kevin puts the spider on the dudes face. And the weird lonely neighbor that the kids are scared of.....that's future me.
Elf - Because Zooey Deschanel is freaking hot and I honestly just like the movie.
Scrooged - Bill Murray is in it and Bill Murray is funny.
When Harry Met Sally - Because I'm a hopeless romantic. I always get teary when Harry is alone on NYE and realizes that he loves Sally, and then runs to the party to tell Sally he loves her. RUN HARRY!!! RUN!!! I'm getting weepy now as I write this.
Star Wars Trilogy (original) - Because it's Star Wars. Lightsabers,the Millenium Falcon, Stormtroopers...... it's Star Wars.
