M. Night Shyamalan's latest movie 'Knock at the Cabin' follows an idyllic family holiday that turns into a post-apocalyptic nightmare.
Here Brian Lloyd asks Night why he decided to go in a different direction with the ending compared to its source material (the novel 'The Cabin at the End of the World' by Paul G. Tremblay).
Night also tells us what he might do if put in a similar situation.
'Knock at the Cabin' is out in cinemas in Ireland on February 3rd.
