Production Studio
Fantasy Films Production Company
Scour the Internet for the "Fantasy Films Production Company" and you're not going to find much. Despite the success of One Flew Over the Cuckoo's Nest, this production company never did a whole lot outside of this movie. Sure, they did a version of Lord of the Rings, but it wasn't the super famous one.
… And that's about it for Fantasy Films. But still, that makes the success of this movie all the more impressive, don't you think? A big movie, from an itty-bitty production company? It appears One Flew had iconoclastic origins to match its iconoclastic star.
