"The froth of days") is a 2013 French surrealistic romantic science fantasy tragedy film co-written and directed by Michel Gondry and co-written and produced by Luc Bossi [fr], starring Romain Duris and Audrey Tautou.

It is an adaptation of Boris Vian's 1947 novel with the same French title, translated Froth on the Daydream in English.

One day while having lunch with Chick, Chick tells him that he met a girl named Alise with whom he has a common passion: the writer Jean-Sol Partre (a spoonerism of Jean-Paul Sartre who was Boris Vian's friend).

The screenplay was written by Luc Bossi and Michel Gondry and based on the 1947 novel Froth on the Daydream by Boris Vian.

[9][10] Mood Indigo was produced by Brio Films, with co-production support from France 2 Cinéma, StudioCanal, and the Belgian company Scope Pictures.

The critical consensus reads, "Mood Indigo is far from Michel Gondry's most compelling work, but it doesn't skimp on the visual whimsy and heartfelt emotion fans have come to expect".
