You know... Lego has so many different sub-brands, I'm surprised they don't just make a movie based on something they made up anyway. Bionicle, Ninjago... they could literally just come up with a random Lego based toy line and make a film of that. I'm just surprised that they didn't.
This seems like some sort of Toy Story thing with Lego. It doesn't sound that bad... but like I said, all they need to do is make up some toy line with a deep back story and make a movie of that.
