If you loved Batman Unlimited: Mechs vs. Mutants, try Superman: Brainiac Attacks
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Curt Geda, and they sit in Action / Animation / Science Fiction territory. If that's the register that drew you to Batman Unlimited: Mechs vs. Mutants, the second film will land in a comparable space — through a different lens.
What Superman: Brainiac Attacks is
Here's a DC Comics joint that probably seemed like a good idea at the time. Lex Luthor, peeved that Superman gets all the glory, teams up with Brainiac to take him down. It might not be canon, but it's definitely a movie.
