With so many great films in the making I am so happy that this is happening. Ever since we saw 'The Lego Movie' it was bound to happen. Batman was one of the best characters in the film, which makes it even more interesting for us to get all excited about this new feature in the making.
Watch this teaser trailer below which is based at Wayne manor when Alfred interrupts Batman while he's reminiscing on the past.
Oh wait it looks like the Justice League are also featuring in this film along side Batman in this epic LEGO adventure, how cool is that!
