Folly to be Wise (1952) - Alastair Sim, Roland Culver

Directed by Frank Launder. Army chaplain Captain William Paris (Alastair Sim), who is head of entertainment at a base, is trying to figure out how to entertain the troops. Unsure of what will rouse the crowd, Paris creates a 'brains trust' (see comment below) featuring local experts - including a professor, a painter (Roland Culver), and the painter's wife (Elizabeth Allan) - to go on stage and answer questions posed by the soldiers. But when the topic turns to matrimony, problems in the artist's marriage become apparent to all.
