Arriving in Cineworld this Friday, The Mercy recounts a remarkable true story of determination and ambition.
The film centres on amateur sailor Donald Crowhurst (Colin Firth), whose decision to embark on a solo, round the world catamaran race had extraordinary consequences. Rachel Weisz plays Crowhurst's devoted wife Clare in a powerful new drama from The Theory of Everything director James Marsh.
Marsh, Firth and Weisz talk us through the making of the film in this behind the scenes look. Check it out below.
