YouTube filmmaker MonsieurCaron, we thank you. The Lego Simpsons introduction video, featuring characters from The Lego Movie is brilliant.
The film, made using real Lego bricks, copies a chunk of The Simpsons introduction first with Simpsons characters, then with Lego Movie stars. The two are then finally combined on an extended version of The Simpsons couch.
While this is great it'll be overshadowed when the official Simpsons episode, created entirely out of Lego, arrives. This will be aired to mark the show's 25th birthday in May.
MonsieurCaron's BrickFilms movies, of which there are plenty, can be found on his Facebook page.
