The opening titles for this film is a shot-for-shot remake of the opening titles for the 1989 Batman film. In LEGO form.
The Joker's line "Where does he get those indestructible toys?" is a play on a line from the 1989 Batman movie. When Batman escapes from the Art Museum with Vicky Vale using a zipline gun, the Joker, (Jack Nicholson), turns to one of his henchmen and petulantly asks "Where does he get those wonderful toys?"
The scene where The Joker's remote detonation fails at first, is similar to Heath Ledger's Joker in The Dark Knight. In The Dark Knight, The Joker's detonation fails to blow up the hospital at first, after which he shakes the detonator a couple of times, and following this the hospital is finally destroyed.
Troy Baker is the first actor to portray both Bruce Wayne/Batman and The Joker respectively, as he is Bruce Wayne in this film and The Joker in 'Assault on Arkham', 'Batman Unlimited' and the video game 'Arkham Origins'. He has also voiced Harvey Dent/Two-Face.
The film is partly comprised of cutscenes from the second LEGO Batman Videogame. All the original actors from the game return for the newly animated segments.
