Welcome To Derry is currently airing its first season, with no confirmed news at the time of writing (October 2025) for season two being greenlit.

However, co-creators Andy and Barbara Muschietti have revealed they have plans for a three-season anthology.

Season one will have nine episodes in total – with the episodes dropping at the same time on Sky Atlantic as they do on HBO in the US.

Welcome to Derry has been rated 18 – meaning it has been deemed suitable for adults only due to its mature content.

This includes:

• Extreme scenes of body horror (including dismemberment)
• Prominent use of blood and gore
• Themes of child abduction
• Scenes intended to scare and cause anxiousness (including jump scares)
• Scenes of violence – including supernatural violence
• Some use of nudity
• Use of profanity

Welcome to Derry is airing weekly on Sky Atlantic and NOW in the UK, and HBO in the US.

The release schedule for the episodes is as follows:

• October 27th
  • Episode 1
• October 31st
  • Episode 2
• November 9th
  • Episode 3
• November 16th
  • Episode 4
• November 23rd
  • Episode 5

If you’re already a Sky subscriber, you will get complete continuity of the service at no extra cost via the Max app. The new deal means Sky and NOW customers benefit from more content through bundled access to the streaming service that will exclusively feature new HBO Original and Max Original shows and more.

And in the case of Welcome to Derry and a range of other series, as part of Sky’s new deal with HBO, customers will continue to find shows such as House of the Dragon, The White Lotus, The Last of Us, and any new series aired before the end of 2025, on Sky Atlantic and through Sky’s On Demand service.

Cecile Frot-Coutaz, CEO of Sky Studios and chief content officer of Sky, said: “What’s really good about the deal that we struck is that if you’re a Sky subscriber, at no additional cost, you will have access to the Max app within your Sky platform. So if you’re already a Sky subscriber, you have complete continuity of service. Actually, you probably have more because Max will have more content than what we have today with the HBO shows and the Warner Bros. films.

“It’s going to be completely seamless for those customers, so you’ll have a really rich experience, and that’s at no additional cost.

“Any show that we’ve had historically on our channels you’ll continue to get on the channels, including future seasons of The Last of Us and The White Lotus.”

In addition, NOW UK and Ireland Entertainment members will also receive bundled access to the ad-supported version of Max, seamlessly integrated into the NOW experience alongside other premium content. They will also continue to get the existing series which were available on Sky as part of their subscription.
