Tim Burton is without a doubt one of the most celebrated and eccentric directors in Hollywood. He is known for his brilliant storytelling and unique visual style as well as for his bizarrely charming characters. While Burton is fascinating in his own right, his movies are even more fun and enriching to delve into, as he regularly shows careful attention to intricate visual and narrative details.
Perhaps because of Burton's meticulous artistry, fans have put together a shared universe theory that connects all his original works, and it actually seems pretty plausible. While films that are part of other franchises - such as Batman - are not included, the theory does consider works Burton didn’t direct but had a large role in creating, such as The Nightmare Before Christmas. If it turns out to be true, it finally explains why all Burton's projects look so similar.
