Alexander Skarsgard turned heads in a backless halterneck shirt and leather lace-up pants at a gala screening for his X-rated BDSM film Pillion.
Pillion, which stars Skarsgard and Harry Melling, 36, who played Dudley Dursley in Harry Potter, is a gay BDSM-themed romance from first-time feature writer-director Harry Lighton.
The film explores the BDSM relationship between a gay biker and a parking attendant - with the project earning rapturous applause at the premiere.
And Skarsgard made a statement on the red carpet at the premiere at the Headline Gala screening during The 69th BFI London Film Festival at The Royal Festival Hall on Saturday evening.
Skarsgard showed off his toned arms in a fully backless white halterneck shirt with a black tie, as well as a pair of leather straight leg trousers with a lace-up fastening at the crotch.
He joined Scissors Sisters star Jake Shears on the red carpet, as well as posing for snaps with the rest of the Pillion cast - who were also wearing leather.
After receiving critical acclaim at Cannes Film Festival, it was revealed Pillion was heavily edited down due to its graphic nature.
The movie received an eight-minute standing ovation, but director Lighton admitted that the version screened at the iconic film festival had been edited down significantly due to its graphic sex scenes.
'It was purely because I didn't want to push the audience into feeling they were being deliberately shocked by an image,' he explained to Variety.
'So for example, there was one close up of a dk, a hard dk ... like down the barrel of the lens.
'And after watching the film on that "fk-off" screen I thought, yeah, cutting it was probably the right decision!'
Skarsgard chimed in: 'There's definitely a raunchier version of this movie ... what you've seen is the family friendly version... there's also the Alexander Skarsgard cut.'
Lighton admitted that Pillion may have needed to undergo even more edits to ensure that it could get a US release.
A synopsis reads: 'Colin, a timid man, meets Ray, a confident biker gang leader, who initiates him into a submissive relationship, challenging Colin's mundane existence and prompting personal growth through their unconventional dynamic.'

Before the screening, director Lighton said he wanted the film 'to make you laugh, make you think, make you feel and make you horny.'
The film features explicit sex scenes and kinky BDSM costumes but Cannes audiences were still lapping it up.
Melling stars as shy Colin, whose humdrum life in the suburbs is blown apart when he meets Alexander's character Ray.
Ray strikes up a sexual relationship with Colin and integrates him into his queer biker milieu, injecting his life with a fresh dose of excitement and mystique.
However Colin eventually starts to feel stifled by the fact that he always has to occupy the submissive role in his dynamic with Ray.
Skarsgard has spoken freely in the past about how comfortable he is playing nude scenes, quipping to uInterview: 'I'm Scandinavian, godda*it! We love to be naked.'
The Swedish hunk is also no stranger to gay sex scenes, thanks to his star-making turn on the vampire show True Blood.

One of the scenes was with heterosexual actor Theo Alexander, whose anxiety Alexander had to help assuage before they shot the sequence.
'He's also a straight guy and he was nervous; he had never kissed a guy before,' Skarsgard explained in an interview with PrideSource.
He said to Theo, 'Look at the scene. It's this nemesis and he comes in and then it gets seductive and you think they're gonna make love and it gets into that and then suddenly my character stabs him in the back and he explodes.'
The actor added, 'In two minutes, look at this emotional rollercoaster we're taking the audience on. If we commit to this, it’s going to be an amazing scene and we’re going to be very happy with it forever. If we hold back, that’s when it gets awkward.'
Skarsgard is himself heterosexual and is in a long-term relationship with Swedish actress Tuva Novotny, with whom he welcomed a baby in 2022.
