Channel 4 has released a trailer for its new gay drama It's A Sin starring Olly Alexander and Neil Patrick Harris.

Stephen Fry and Keeley Hawes also appear in the show - previously known as Boys - which is set in the 1980s amid the backdrop of the AIDS epidemic.

The five-part series comes from Russell T Davies, known for Queer As Folk, Doctor Who and Cucumber, and will air on Channel 4 early next year.

"I lived through those times, and it's taken me decades to build up to this," said Davies. "And as time marches on, there's a danger the story will be forgotten.

"So it's an honour to write this for the ones we lost, and the ones who survived."
