Fans of dark romantic comedy-dramas are in for a real treat with this gripping new film.

Pillion only arrived in cinemas last year, yet it has already made its way on to at least two streaming platforms.

It is available to those with a standalone subscription to HBO Max, as well as those with Sky Cinema or a Movies Pass through the NOW platform.

According to its synopsis, the film centres on Colin, a shy and unassuming man who encounters Ray, a magnetic, strikingly handsome biker who completely sweeps him off his feet, drawing him into a submissive relationship.

This turns Colin’s humdrum life on its head and sparks personal development through their unconventional dynamic.

Harry Melling, widely recognised for his portrayal of Dudley Dursley in the original Harry Potter films, takes on the role of Colin, while Alexander Skarsgård — known for True Blood, Succession, and Murderbot — steps into the shoes of Ray , reports the Mirror.

Upon its release, the film proved a resounding success with critics, earning a near-perfect 99% on Rotten Tomatoes. One review declared: “Pillion is a bold, bawdy film told through small looks and big feelings. It broke my heart and put it back together again.”

Though another cautioned: “Pillion isn’t a film for everyone. But those who know what it means to grovel for their beloved…will find in a subject for analysis in Pillion’s erratic relationship and outlandish romance.”

Another agreed but also drew attention to how it approaches its subject matter.

The reviewer wrote: “While the cringe is strong (and deliberate) in many scenes of Pillion, Lighton makes it clear that kink isn’t an embarrassing detour for Colin – it’s how he comes to know himself. For him, in a very real sense, submission becomes empowering.”

Fans who have already watched the film have been equally bowled over. One viewer shared their thoughts online, saying: “Unforgettable film in so many ways. Yes, it’s explicit, but that isn’t the lasting footprint of this film. I left the cinema having been enlightened, embarrassed, happy, and so very sad.

“It’s a masterclass in the subtlety of truly great acting where so few words are needed to elicit such emotion from an audience. There won’t be Oscar nominations as it’s a small, independent film with a small budget, but there really, really should be.”

While another remarked, “A beautiful, unflinching look at queer BDSM life. While it might not be for some (the faint-hearted), it is soulful enough to warrant consideration of anyone capable of empathetic, non-discriminatory understanding of joy in all relationships, and ultimately how fleeting and precious it is.”

One viewer offered their verdict, posting: “It is a rare film, dealing with a theme seldom explored in cinema and, above all, very raw. I have seen some opinions suggesting that the ending was unpleasant. For me, the ending was one of the best parts.”

Pillion is streaming on HBO Max, Sky Cinema and NOW for those with a movies pass.
