This an old movie, a comedy. It's about a wealthy playboy who's interested in a nice girl. Also, a broke man wants to marry a wealthy but nasty woman. They all meet at a party. The nasty lady says she'll marry the broke man if he'll live with her in her country house as a "trial marriage." Both couples go to the house )I think it's in Scotland). The servants are all shocked at the immorality and quit. The people have no idea how to cook or clean or take care of themselves. There is a big storm, and they run out of food. One of the men accidentally winds up in a woman's bedroom, and there's a big misunderstanding and fight. The playboy sets off in a boat in the storm to get food, or to just leave or something. The broke man and the nice girl hit it off, and get engaged when they realize they're both nice people who can actually do some work and solve problems. The playboy is stuck marrying the nasty lady.
Based on a 1926 play by Frederick Lonsdale, this was English actor Clive Brook’s only directorial effort. Sure the release date's off by a decade, but I'm fairly certain this is the film you saw.
