If you loved The Big Lebowski, try Hail, Caesar!
A bridge between a film you've already seen and one most people haven't. Hail, Caesar! has roughly 3.0× fewer votes than The Big Lebowski — 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 Ethan Coen, Joel Coen, and they both carry the bittersweet, playful mood tags, and they sit in Comedy / Crime territory. If that's the register that drew you to The Big Lebowski, the second film will land in a comparable space — through a different lens.

What Hail, Caesar! is
1950s Hollywood, a movie set, a missing star's empty trailer. A frantic studio, a kidnapped actor, a ransom note. The Coen brothers delight in this tangled web of old Hollywood.
