I started to watch it, but it was too dismal knowing about our own current government downfall and traitors running things. And in the film, the Americans and British have the German Captain aboard. One of the Americans wanted to throw the German overboard, but in the story, the German is allowed to live. One funny scene in the movie is a cameo by Hitchcock in a newspaper ad for losing weight.

Hitchcock's Lifeboat based on novella commissioned by Hitchcock and written by John Steinbeck
Eight British and American civilians, service members and United States Merchant Mariners are adrift in a lifeboat after their ship and a German U-boat sink each other in combat. Willi, a German survivor of the U-boat, is pulled aboard. During an animated debate, engine room crewman Kovac demands the German be thrown out to drown. However, the others object, with radioman Stanley, wealthy industrialist Rittenhouse and columnist Connie Porter succeeding in arguing that he be allowed to stay.
Hitchcock's cameo in Lifeboat (1944) occurs about 25 minutes into the film, where he appears in a newspaper advertisement for the "Reduco Obesity Slayer" weight loss system, manufactured by fictional The Reduco Corporation.

Steinbeck's complaints about Lifeboat
After Ernest Hemingway had turned down Alfred Hitchcock's offer to write the story for Lifeboat (1944), Hitchcock approached another novelist, John Steinbeck. Steinbeck accepted the offer and eventually gave Hitch a novella. Hitchcock then had several writers turn Steinbeck's novella into a workable screenplay, among them MacKinlay Kantor, Ben Hecht, Jo Swerling and Hitchcock's own wife Alma Reville. In the end, Swerling was the only one credited for the screenplay, while Steinbeck was credited for having written the original story.
