The network has partnered with Backyard Cinema, for a Game of Thrones-themed takeover at the venue in South London.
Set in a snow-clad castle fit for a Targaryen, guests will be invited to experience two episodes of Game of Thrones season seven. They will venture through a frozen ice cave to discover all the Citadel Apothecary has to offer, as well as getting the chance to sit on the iron throne before relaxing onto giant beanbags to enjoy the show.
The event takes place on 12 December and people will need to enter a competition to be in with a chance of attending.
Ian Fullerton, vice president of international marketing at HBO, said: "Working with Backyard cinema for a Game of Thrones screening is a great way to bring the show alive, encouraging new fans to come into the franchise and celebrating the physical release with some of the great moments from season seven."
