I’ve seen Elf probably a dozen times — it’s one of my favorite Christmas movies to watch with the kids — but I never bothered to watch the behind-the-scenes featurettes, so I was delighted by this clip from Netflix’s The Holiday Movies That Made Us that shows how they used forced perspective to make Will Ferrell seem gigantic:
I love practical effects like this. (Director Jon Favreau wanted the movie to look timeless, so he stayed away from too much CGI that might date the movie.) The forced perspective technique is also how they got Hagrid to look so huge in the Harry Potter movies and the hobbits so small in The Lord of the Rings.
