The Navigator

Director: Donald Crisp and Buster Keaton

IMDB: https://www.imdb.com/title/tt0015163

Review: Just the right levels of silly with an ending gag that casually drops one's jaw.

Watch it if: You want to see how many gags can be squeezed out of a fairly simple premise.

And if you liked: Three Ages, Our Hospitality, Sherlock Jr.
