If you loved The Bugs Bunny/Road Runner Movie, try Haredevil Hare
A bridge between a film you've already seen and one most people haven't. Haredevil Hare has roughly 3.8× fewer votes than The Bugs Bunny/Road Runner Movie — it's a deeper cut, not a mainstream recommendation. 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 Chuck Jones, and they both carry the playful mood tag, and they sit in Animation / Comedy / Science Fiction territory. If that's the register that drew you to The Bugs Bunny/Road Runner Movie, the second film will land in a comparable space — through a different lens.
What Haredevil Hare is
Bugs Bunny gets launched to the moon for a routine test and immediately starts a turf war with a mustachioed commander armed with a planet-ending device. The rabbit casually thwarts a global annihilation plot while sampling lunar cheese supplies. A 7-minute sprint through gags that somehow explains its own plot before the credits roll.
