So when you go see LEGO Batman, don’t worry about shared universes or franchise continuity or character rights.
While this multiverse could hypothetically include all DC properties, including the DCEU, it’s unlikely the Arrowverse will cross over with its big screen cousin, but some new cross-promotions have LEGO Batman meeting up with LEGO members of the Arrowverse.
Thanks to the Flash and the Speed Force in the Arrowverse, the multiverse has been brought to DC television.
Fun bits like this are a great example of the appeal behind the LEGO franchise, and likely a big reason the movie has rave early reviews.
