If you loved Sherlock Jr., try The Navigator
A bridge between a film you've already seen and one most people haven't. The Navigator has roughly 4.2× fewer votes than Sherlock Jr. — 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 Buster Keaton, and they both carry the playful mood tag, and they sit in Action / Comedy territory. If that's the register that drew you to Sherlock Jr., the second film will land in a comparable space — through a different lens.
What The Navigator is
A 1924 playboy boards a ship intending to propose, only to find his rejected sweetheart already stowed away. Their accidental oceanic partnership grinds gears between slapstick and sincerity. A silent-routine time capsule that gets by on goodwill and ocean liners.
