Lead actress Mireille Darc recounts her first encounter with Godard before shooting: "The meeting takes place, Godard barely speaks to me, looking exasperated behind his big glasses- and yet, yes, he agrees, we're going to work together.

The intertitle before the slaughter of the pig reads "Thermidor", which is the name of the month of the French revolutionary calendar when Robespierre was executed.
