I'm not particularly a movie watcher but The Cat Returns is pretty good. Extremely weird and wacky but good in its own way. Any other favourites of mine are all Tim Burton films (or at least the majority)
Phantom of the Opera is definitely one of my all time favorites. I LOVE the entire Harry Potter series, but my favorite is the Deathly Hallows pt2. Lord of the Rings and the Hobbit are also favorites! Oh, and WALL-E
For me, it's probably either Stardust or Balto, with The Iron Giant coming in a close third to the first two. Depends on the day - if I want Feels, it'll probably be Giant, but if I want to cheer up (like today) it'd be one of the first. Loads of other films on the list, but since we're talking favorites...
Bump. Yeah! The return of the faded thread ! I've just watched again "Pan's Labyrinth", from Guillermo del Toro... I had forgotten how so beautiful, and at the same time so dark that film was. So like a real fairy tale... note : Do NOT watch it if you don't want to see death, violence and blood, though.
