"Love Circle", literally "Let's Say, an Evening for Dinner") is a 1969 Italian drama film directed by Giuseppe Patroni Griffi.
[1] Michel (Jean-Louis Trintignant) is a successful bourgeois playwright who fantasizes an affair between his beautiful wife, Nina (Florinda Bolkan), and his best friend, Max (Tony Musante), a bisexual actor.
While Nina is occupied with Max, Michel drifts into an affair with a rich, but lonely, single woman (Annie Girardot).
The four meet regularly for dinner at the home of Michel and Nina where they indulge in bored, amoral conversation.
It's then that Michel decides to invite Ric into the circle, as they go on meeting at dinner and playing their games of love and seduction.
