Elsa Keslassy International CorrespondentJean Dujardin, best known for his roles in light-hearted films such as the Oscar-winning “The Artist,” plays the fierce boss of a highly-secretive police brigade that tracked down the assailants of the 2015 Paris attacks in Cedric Jimenez’s “November.”Written by Olivier Demangel (“Atlantics”), the fast-paced and tense thriller world premiered at the Cannes Film Festival and is being represented in international markets by Studiocanal. Jimenez, who was at Cannes last year with another action-packed police thriller, “The Stronghold,” sat alongside Dujardin with Variety during the festival to discuss the genesis of “November,” how the ensemble cast — including Dujardin, Sandrine Kiberlain, Anais Demoustier and a flurry of fresh faces — worked together, and what it meant for them to tackle this recent tragedy.
