When the first pictures broke of psychological thriller Shut In, which stars Naomi Watts (The Impossible) and Jacob Tremblay (Room), the initial feeling seemed to be that the pair would be facing danger together.
Shut In finds Watts as a child psychologist still recovering from the aftermath of a tragic car accident that left her husband dead and her son (Charlie Heaton) in a comatose state.
She agrees to foster a troubled boy (Tremblay), but as a strong winter storm whips up around her isolated, rural New England home, he suddenly disappears. Yet it is when he is presumed dead that weird things start to happen...
Farren Blackburn directs this one, working from Christina Hodson's script. Shut In will arrive in US cinemas on 11 November, but has yet to secure a UK release date.
