Claire Foy and James McAvoy will star in the new thriller [my son] (My Son). The film is adapted from the 2017 French film of the same name, and the original director Christian Carrion will direct the English version of the film. McAvoy will play the father of a missing son who goes to the town where his ex-wife (Foe) lives to find the answer to the mystery. In order to show the confusion, McAvoy will not get the script, but will improvise according to the development of each scene. STXfilms won the rights to distribute the film in North America.
