The trailer for 1941.
Late 1941, a young woman goes for a midnight swim, alone and naked (in a nod to the opening of the film Jaws) to find a Japanese submarine surfacing under her. She holds on to the periscope as it rises. The submarine crew realizes they have arrived where they intended to be, Hollywood, and the vessel submerges once again while the girl swims to safety.

A landing party captures a local timber merchant, Hollis Wood; on board the sub, they see he has a small Cracker Jack compass that he swallows. Wood escapes, while in Los Angeles, Major General Stilwell goes to see the feature film Dumbo.
