Will Bruce Wayne's parents die in Lego form?
Lego is making a huge comeback in the last few years (Note: I'm an adult and haven't played with Lego's in a while. Have they always been popular with kids?), certainly not hurt by THE LEGO MOVIE being a massive success. How do you make even more money? Why, by centering your next film on one of the most recognizable comic characters of all time.
Will Arnett returns to voice Bruce Wayne/Batman, and from the sounds of the trailer, it doesn't look like it will be taking itself too seriously. It's a novel concept.
