Are you a huge Game of Thrones fan? Then you'll probably want to be in London starting on Monday, November 27 and have your calendar cleared for most of the week. HBO, in order to help promote the release of Game of Thrones season 7 on Blu-ray, is showing a free marathon of every single episode of the hit series on the big screen over the course of four days. That's right. All 67 episodes. And free pizza is involved.

The event is taking place at The Prince Charles Cinema in London from November 27 through November 30. The event is totally free but, as you can imagine, demand was high. Tickets for the big screen Game of Thrones marathon are already sold out. But some very lucky fans are going to get to spend four days experiencing the world of Westeros on the big screen. Considering how cinematic Game of Thrones is, that's likely to be a great experience. Here's a description of the event from the Facebook event page.

"We welcome HBO UK's award winning phenomenon that is Game of Thrones as we host a monumental marathon screening of all seven seasons. To mark the release of Game of Thrones: The Complete Seventh Season and The Complete Seasons 1 - 7 Boxset on Blu-ray™ and DVD, die-hard fans of the record-breaking show can view it all in its entirety on the big screen for the very first time for four days and nights. The non-stop, cinematic takeover will begin at 7pm on Monday 27th until 6pm on Thursday 30th of November 2017, when lucky Game of Thrones fans will be able to experience this unique one off event."

Not only do those attending the event get to watch the entire Game of Thrones series in a theater for free, but HBO has partnered with MOD Pizza, who will show up during evening dinner breaks of the marathon to give people food. Plus, fans that survive the entire screening will go into a draw to win a year's worth of pizza. It's worth mentioning that the Game of Thrones marathon will have breaks built in, so those attending won't have to try and sit for 63 hours straight, which is how long all of the episodes will take to watch with no breaks at all. That's just about two and half days and this marathon will last for four. So there's plenty of time to get a little sleep at least.

Unfortunately, HBO isn't holding events like this at any other theater, but who knows? They could announce more screenings, so keep an eye out. According to the Facebook event page, some select tickets will be made available on the day of for each of the four days, so you still have a chance to possibly see some of the marathon.
