In the irreverent spirit of fun that made "The LEGO Movie" a worldwide phenomenon, the self-described leading man of that ensemble –LEGO Batman– stars in his own big-screen adventure: "The LEGO Batman Movie." But there are big changes brewing in Gotham, and if he wants to save the city from The Joker’s hostile takeover, Batman may have to drop the lone vigilante thing, try to work with others and maybe, just maybe, learn to lighten up.
In the fourth trailer, a brief scene makes out what appear to be 3 Gremlins attacking the Batwing
Also, the Extended TV spot there were some Daleks near the main energy source at Gotham Energy (However, they look different to their Dimensions appearance), and at it's ending Flying Monkeys appeared flying in the Batcave. Lord Voldemort also appears in the movie.
Bruce Wayne's counterpart in this movie is different than his LEGO Movie counterpart.
