Director Chris McKay’s The LEGO Batman Movie is unquestionably a follow-up to The LEGO Movie – featuring not only the same animation style but also a shared lead character — but the connections are surprisingly slim.
As you might guess, this approach was taken for a specific reason, and it’s why Chris Pratt’s Emmet and Elizabeth Banks’ Wyldstyle don’t wind up making cameos in the animated blockbuster: the filmmakers really wanted it to specifically be a Batman movie.
Will Arnett’s incarnation of the Dark Knight is clearly the same, and there are mentions of Master Builders, but the titular hero pretty much lives in his own world beyond that.
