Olly Alexander said: “I feel like the luckiest boy 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 years old. 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.”
"Russell’s scripts chart the highs and lows of this time so beautifully and deftly, it’s an honour to help tell this story.”
