Colin Firth reportedly had to reshoot a tender love scene in his latest film - but not because the actor fluffed his lines.

It seems that filming was interrupted by a loud fart on set.

Colin told the Sun newspaper that he and co-star Helen Hunt were hard at work on the "emotional heart" of their new film, Then She Found Me, when a flatulent crew member let rip.

"It was not silent, it was deadly," Colin told the paper.

"There was this silence, this paralysis in the room. Helen's character plays my children's schoolteacher and one of the emotional hearts of the film is when she comes to sleep on the floor of the room where I am with the kids.

"It's very, very quiet and we can't speak too loudly because the kids shouldn't see their schoolteacher with their dad. There was a camera at floor level because that's where we were - then somebody down there broke wind incredibly loudly.

"Helen, who was in my arms said: 'What just happened?' Some very noble soul put his hand up and said they did it."
