Quebecois actor Marc-Andre Grondin is set to star alongside French actress Laura Smet in Gabriel Le Bomin’s second film Insoupconnable for Paris-based Films Oblige and StudioCanal.

Le Bomin’s script is adapted from the French bestseller of the same name by Tanguy Viel. The film goes in front of the camera on October 19 in France and Switzerland.

Grondin told Screen International he and Smet play a young couple posing as brother and sister who plot to fleece an older man, played by Charles Berling. Then the older man’s brother, played by Grégori Dérangere, enters the picture. The title, which translates as “above suspicion”, is deeply ironic.

Le Bomin’s previous film Les Fragments D’Antonin was nominated for best first film at the Cesar Awards in 2007.

Grondin recently wrapped production on Jean-Paul Salomé’s Chameleon and Christopher Thompson’s Bus Palladium, both of which will be in cinemas in France next year. His latest Canadian film, the thriller 5150 Rues Des Ormes, is in cinemas in October.
