Momentum Pictures has picked up all UK rights to Nanni Moretti's Palme d'Or winner The Son's Room.

The story of a middle class Italian family dealing with the death of their son will have its UK premiere at the London Film Festival on Nov 17, with Moretti attending.

Momentum bought the film from French-based sales agent Wild Bunch in a deal negotiated between Sally Caplan, Momentum's senior vice president of acquisitions and business affairs, and Carole Baraton, Wild Bunch's sales manager.

"This remarkable film was certainly highly sought after by a number of UK distributors following its Cannes debut," said Caplan. "It is beautifully directed, acted and, considering its subject matter, life-affirming."
