'Cabbage Soup') is a 1981 French science fiction comedy film directed by Jean Girault, based on the 1980 novel by René Fallet.
Surprised, Le Glaude communicates with the alien through rough sign language and then sends him off with a canister full of cabbage soup.
Worried about his friend, Le Glaude tricks him into hanging himself while he secretly cuts the rope so that he falls when he puts his weight on it.
Meanwhile, the mayor of the rural town decides to modernize and plans a new housing project directly on the old men's land.
He tells Le Bombé about their option, who is at first unconvinced, but opens up to the idea when he sees the communicator the alien has left.
