Who could play the nude wrestling scene today?
From a woman's POV I would like to see Alexander Skarsgård & Ryan Gosling in this scene.
Could such a scene be filmed today or would it be viewed as pornography?
It was remade for British television in 2011 - a much longer and more faithful (but arguably less beautiful and cinematic) adaptation of Lawrence's novel than Ken Russell's 1969 version.
This remake had the nude wrestling scene intact and was even more graphic in terms of nudity. There was no discreet use of shadow and firelight this time. The new version has the nude wrestling (between actors Rory Kinnear and Joseph Mawle, playing Birkin and Gerald) taking place in broad daylight in the spraying surf of the sea shore.
No it wasn't seen as pornography. Nudity isn't pornography. Modern British audiences don't have the issues with nudity that (for instance) rather more puritanical American audiences seem to have with it.
