LONDON — Toby Jones has joined the cast of “Leave to Remain,” the fiction feature debut of helmer Bruce Goodison.

Jones joins a cast that mixes professional actors with young people from migrant and refugee backgrounds in the coming-of-age drama. The film, which has started lensing in London, follows a group of teenagers from disparate countries, thrown together to build a new life in Blighty’s capital.

Goodison, best known for his docu work for television including “Flight 93: The Flight That Fought Back,” “Bid Laden: Shoot to Kill” and the BAFTA-winning docu skein “Our War,” researched the lives of young people seeking sanctuary in the U.K. over three years for the project.

Jones was recently seen in “Snow White and the Huntsman,” “Berberian Sound Studio” and as Alfred Hitchcock in TV movie “The Girl,” about the master of suspense’s relationship with his “The Birds” and “Marnie” star Tippi Hedren. He recently finished work on Susanne Bier’s “Serena,” starring Jennifer Lawrence and Bradley Cooper, and is reteamed with Lawrence once again in “The Hunger Games: Catching Fire,” in which he reprises his role as Claudius Templesmith from the first film.
