The 39-year-old actor has revealed that the horror movie he co-wrote, produced and starred in alongside wife Emily Blunt - with whom he has daughters Hazel, four and two-year-old Violet with -has had a huge impact on him and his family and he doesn't think a film will ever have the same effect on him.

Speaking at Deadline's The Contenders London event, he said: "This movie has changed my life in every single way, not just my career; I've not given my total sense to anything before, and I don't mean that I've been lazy, but there was something extremely personal about this movie. I said to my wife, 'I don't think it ever will be like this again'. And my wife, who is a brilliant sage, said, 'Of course there won't. This is special and we did it together and there was something about it for your daughters.' "

The film follows John and Emily as a married couple who must protect their children - played by Noah Jupe and deaf actress Millicent Simmonds - from monsters who are blind but have an acute sense of hearing.

'The Office' actor has previously stated that the right casting of his on-screen daughter was key to the whole film.

He said: "In my first call to Paramount I said, 'I have to cast a deaf actress for all the reasons, not just the obvious one, to get an organic performance.' But also I wanted a partner in crime. I wanted her to walk me through her life. To say she is special is an understatement. We believe she's an angel."
