The Awful Truth (1937)

Directed by Leo McCarey

Unfounded suspicions lead a married couple to begin divorce proceedings, whereupon they start undermining each other's attempts to find new romance.

"Never during our marital bliss did she cause me a moment's uneasiness. Never did I have to ask, "Lucy, where have you been, what were you doing?". I always knew."

The Awful Truth is one of the great American comedies, but it’s also a mighty and mysterious film about relationships, which are composed of nesting negotiations—performances—that leave scars.
