Comic Con Luxembourg will return to LuxExpo on 29 and 30 November 2025, uniting fans with pop culture attractions and a star-studded guest line-up featuring Ian McDiarmid, Jason Isaacs, Evanna Lynch, and Jamie Campbell Bower.

Comic Con Luxembourg is set to take over LuxExpo on 29 and 30 November 2025, bringing fans a weekend packed with pop culture, entertainment, and special appearances. According to organisers, this year's edition will once again feature a wide range of attractions spanning comics, manga, cosplay, gaming, films, series, sci-fi, fantasy, and more.

However, one of the biggest draws for fans will certainly be the chance to meet an exciting roster of international stars.

For one, the list includes the legendary Ian McDiarmid, celebrated for his unforgettable portrayal of Emperor Palpatine across multiple Star Wars films, from the original trilogy to the prequels and beyond. If you have ever wanted to be in for a chance to hear the Tragedy of Darth Plagueis the Wise in person, then Comic Con Luxembourg is the place to be.

Harry Potter fans should also be beyond thrilled with the special guests, starting with Jason Isaacs, who gained worldwide fame as Lucius Malfoy, father of Harry's biggest school rival. He has also appeared in Star Trek and more recently featured in the third season of the HBO hit series The White Lotus.

Isaacs will be joined by Evanna Lynch, beloved for her role as the eccentric and kind-hearted Luna Lovegood. Lynch has become an enduring figure within the franchise's fandom, known not only for her performance but also for her advocacy work outside the film world.

Rounding out the guest line-up is Jamie Campbell Bower, who played a young Gellert Grindelwald in the Fantastic Beasts franchise. Campbell has further captivated audiences as the terrifying Vecna in the fourth season of Netflix' Stranger Things and Caius in the Twilight franchise. In Sweeney Todd: The Demon Barber of Fleet Street, Campbell has further shown that he is also more than capable of holding a tune.

The convention will run from 10am–7pm on Saturday, 29 November, and from 10am–5pm on Sunday, 30 November. Get your tickets via this link.
