Karen S Shapiro and Michel Rampal are producing the story of two individuals with complicated private lives who find love after they become neighbours.
Ed Quinn, Ann Cusack, Gina Mantegna, Meredith Scott Lynn, David Youse, Patrick Breen, and Richard Kind round out the cast.
'[The Neighbour] showcases Los Angeles in a new light,' Shapiro said. 'The gorgeous romantic LA skyline and the revitalised Downtown district with its loft condos are key elements of the film.'
France's Laroque previously starred in Ma Vie En Rose and Le Placard, and earned Cesar nominations for Pedale Douce and La Crise.
Modine's credits include Birdy, Short Cuts, Married To The Mob, Full Metal Jacket, Any Given Sunday, and Le Divorce.
