Actor James Norton blacked out while filming Lady Chatterley's Lover
Actor James Norton revealed his role as Sir Clifford Chatterley in the new BBC reincarnation of DH Lawrence's controversial novel was so physically taxing that he blacked out.
In Lady Chatterley's Lover, Norton's character infamously spends the majority confined to a wheelchair, half-paralysed because of an injury sustained in the trenches of the First World War.
The Happy Valley and Grantchester star found himself challenged when he filmed a scene of his character undergoing a treatment involving electric shocks.
"It was quite tough, both physically and emotionally," the actor said at the show's launch in London.
"The physical thing was quite terrifying - I actually had a weird moment. I kind of blacked out at one point and I didn't know where I was. I've never experienced it before."
Norton joked he could appreciate the practical side of an on-screen blackout, saying: "There was one moment when I kind of had to take a bit of a breath. I hope that was used in the edit."
The London-born actor admitted sitting in the wheelchair proved to be another challenge.
"It is a very bizarre thing when you're short of time and can't stand up and walk to the loo," he said, adding: "It was a very eye-opening experience for me personally to sit in that wheelchair hours on end."
BBC One's new drama, which has been adapted by Jed Mercurio, also stars Holliday Grainger as Sir Clifford's wife Constance and Richard Madden as brawny gamekeeper Oliver Mellors.
Viewers expecting racy scenes may well be surprised with the latest adaptation, which is more focused on the tender love than the explicitly sexy love triangle between the three characters.
Mercurio explained: "It doesn't excite me, as a writer, to write some swearing or sex scenes, because they don't have emotional content.
"I wanted to go back to them (Constance and Clifford) falling in love, I wanted to see what they expected the future to be."
He also revealed he chose to ignore previous film adaptations of the controversial novel, saying: "My only real relationship was with the book."
Lady Chatterley's Lover will air on BBC One in September.
