The Lego Movie

How Long It Took: 4 years, or 7 quests to the top of Lord Business’ tower

Why It Took So Long: Animated films tend to take a long time in general, but The Lego Movie took a bit longer than normal, thanks to the extensive script rewrites that needed to be done – much of the original planned film The Piece of Resistance was scrapped and reworked – and all of the detail that went into animating every single Lego brick in the film. And there were a lot of them.

Was It Worth It? Definitely. Everything about The Lego Movie is awesome, and now you have that song stuck in your head. You’re welcome.
