Brickfilm
A Brickfilm is a film made using Lego bricks, or other similar plastic construction toys. They are usually created with stop motion animation though computer-generated imagery (CGI), traditional animation, and live action films featuring plastic construction toys (or representations of them) are also usually considered brickfilms. The term 'brick film' was coined by Jason Rowoldt, founder of Brickfilms.com.
