DC's animated movies are arguably better received than Warner Bros' big-budget live action movies. Teen Titans GO! To The Movies and The LEGO Batman Movie are some of the highest rated DC movies in recent years.
Despite the critical and commercial success of The LEGO Batman Movie, Warner Bros has yet to release a sequel. However, director Chris McKay has revealed that a sequel was being planned right after the first film’s release.
LEGO Batman sequel would’ve been LEGO Justice League
Speaking to Screen Crush, Chris McKay explained that the LEGO Batman sequel would've focused on the Justice League. Following on from the first movie, the sequel was supposed to explore Batman’s relationship with Superman and the rest of the League.
When asked what the general plot of the film was, McKay explained:
“It was a story about the Justice League and where Batman was in terms of the Justice League now, and the struggles they were going through, as well as flashing back to how the Justice League came together. [It also featured] Batman and Superman’s relationship, as well as Batman's relationship to a lot of the other members of the Justice League."
Robin would've had a bigger role
The LEGO Justice Movie was not just a movie about Batman’s relationship with the Justice League. Just like the first movie, the B plot of the movie was going to revolve around Robin. Unfortunately, Chris McKay didn't explain exactly what Robin’s role was. Instead, the director explained:
"And Robin, obviously, there was a really great part for Robin.”
