It’s A Sin was created for Channel 4 in the UK by BAFTA-winning writer Russell T. Davies, famous for hit shows such as Doctor Who, A Very English Scandal and Queer As Folk. It follows the rollercoaster lives of a group of young gay men living through the AIDS crisis in the 1980s and features a star-studded cast that includes Keeley Hawes, Neil Patrick Harris and Stephen Fry, with pop singer Olly Alexander taking the leading role. 

Here's all you need to know about It's A Sin which has now become available to watch on Netflix...

Where can I watch It’s A Sin around the world?

It's A Sin was first shown in early 2021 the UK on Channel 4 (an All4) and on HBO Max in the US. It's now become available worldwide on Netflix and Disney Plus.

It's A Sin plot

The five-part drama It's A Sin begins in 1981 when teenagers Ritchie, Roscoe and Colin first meet in London. After finding themselves thrown together, the boys, along with Ritchie’s friend Jill, share each other’s adventures. But with the new deadly AIDS virus on the rise, their lives are tested in ways they never imagined.

Determined to live and love more fiercely than ever, as the decade passes, together they endure the horror of the AIDS epidemic, the pain of rejection and the prejudices that gay men faced back in 1980s Britain when Margaret Thatcher's very anti-gay Conservative government were in charge.

It's A Sin cast

Olly Alexander, best known for BBC1’s 2019 drama Years and Years, plays 18-year-old Ritchie Tozer, the "golden boy" of his family who’s keeping big secrets from them.

Newcomer Omari Douglas plays Richie’s friend Roscoe, a "wild and brittle" party-boy who’s always on the run, while another newcomer, Callum Scott Howells, stars as Colin Morris-Jones, a quiet and unassuming lad from Wales who’s about to become an apprentice on London’s Savile Row.

Lydia West (Years and Years, Dracula) plays Jill Baxter, Ritchie’s friend from college, who’s described as "straight-talking, funny, and the rock on which they rely."

Look out for Keeley Hawes (Bodyguard, The Durrells) as Ritchie’s mum Valerie, while Shaun Dooley (Gentleman Jack, Broadchurch) plays his dad, Clive.

American star Neil Patrick Harris (How I Met Your Mother, Doogie Howser MD) plays a gay character called Henry Coltrane, Stephen Fry is MP Arthur Garrison, and Tracey Ann Oberman (Friday Night Dinner, EastEnders) plays Carol Carter. Newcomer Nathaniel Curtis plays Ash described as "a faithful friend through thick and thin."

What else do we know about It’s A Sin?

Writer and creator Russell T. Davies, famous for Doctor Who, Torchwood plus Years and Years in 2019, has based this drama on many of his personal experiences. Like the characters in It’s A Sin, he was 18 himself in 1981. Speaking about It’s a Sin he said: "I lived through those times, and it's taken me decades to build up to this. And as time marches on, there’s a danger the story will be forgotten. So it's an honor to write this for the ones we lost, and the ones who survived."

Pop singer and actor Olly Alexander, who stars as Ritchie Tozer, says: "I feel like the luckiest lad in the world to be a part of this project. I’ve been a fan of Russell T. Davies ever since I watched Queer As Folk in secret at 14. His work helped shape my identity as a gay person so I’m absolutely over the moon we’ll be working together. The script was amazing to read, I laughed and I cried a lot, it’s a privilege to be helping to tell this story and I’m so excited."

It's a Sin — the hit song

Yes It's a Sin is a song title. It was a massive hit for legendary British band The Pet Shop Boys back in 1987. It will of course feature heavily in the Channel 4 drama (see the trailer below), along with many other famous hits of the 1980s.

Is there an It’s A Sin trailer?
