Attention all apprentice wizards and muggles alike: the quasi-traditional Harry Potter marathon will be returning to the Grand Rex, for what promises to be 2 emotionally-charged days. In the heart of the Grand Rex’s main auditorium, and the latest addition, Infinite, you’ll be invited to rediscover the 8 films of the cult sage in a sumptuous setting. So, will you be going all out?
The 8 Harry Potter films shown non-stop at the Grand Rex
If you weren’t sure what to do on the weekend of September 6-7, get your diaries ready, because an epic viewing session of the most magical of sagas is on the menu. It’s almost become a custom over the years, as the Grand Rex organizes a Harry Potter marathon retracing the adventures of the most famous Gryffindor, from Philosopher’s Stone to Deathly Hallows Part 2.

The program kicks off on Saturday, September 6 at 10:15 a.m., with the first four films in the saga running until 10:50 p.m. The following day, from 10:30 a.m. to 10:40 p.m., the last four films will be screened. As for the setting, there are two options, neither of which is a bad choice. The Grand Rex offers these screenings in two of its magnificent theaters. You’ll be able to choose between the Grand Hall and its magnificent decor, or the brand-new Infinite room, based on a more premium offer.
The choice is yours! Do you dare to go on the rollercoaster and complete the full marathon?
