Mood Indigo. L'Ecume des jours.
Gondry+Vian+Tautou+Duris+Sy= Epic win. If you don't know what we are talking about, have a look at the trailer published in thisIndiewire article
However, if you too got excited at the thought of Gondry's adaptation of Boris Vian's cult novel, beware of this vaguely cheesy teaser that shows either too much or/but hopefully not what is visible to the eye. French relase just before Cannes Festival, on April 24.
