Superjhemp: A Uniquely Luxembourgish Superhero
De Superjhemp Background
De Superjemp (most commonly spelled Superjhemp) was first launched in 1988 as a superhero in a widely popular comic book series . The character was first created by illustrator Roger Leiner and writer Lucien Czuga. Since then, he has appeared in over 29 graphic novels that have the highest sales rate for Luxembourgish publications.

The Superjhemp Story

Superjhemp is a portly character who can fly and has super strength. His superpowers come from Kachkéis , a cooked cheese that remains one of the most historically popular local products typical in Luxembourg. He flies around with his hands in his pockets, “because every real Luxembourger has his hands in his pockets,” according to his creator, soaring over landmarks like the Rout Bréck to save the day from the latest villainous plot or cosmic catastrophe.
Feature Film and Luxembourgish Production
Because of the comic story’s wildly popular place in Luxembourg culture, it made sense to turn the comic book into a film.
The project was launched by Samsa Films, Luxembourg’s largest film production company, building upon a rich national cinema legacy championed by early local filmmakers like Andy Bausch. The 2018 film’s producer is Claude Warringo, and the director is Félix Koch, both native Luxembourgers. It took 30 days to shoot the film. However, with a 3.5 million Euro budget, De Superjhemp Retörns had the highest budget of any Luxembourgish production in history. The movie also had the highest box office take-home for a Luxembourgish film in the country’s history, beating out American superhero blockbusters like Avengers: Infinity War and The Incredibles 2. It is also considered the most popular film in the Luxembourgish language.
De Superjhemp Retörns
In De Superjhemp Retörns, André Jung, who is well known on German TV, plays our hero. In the film, it has been a long number of years since the “Little Duchy of Luxusbuerg”, a playful nod to a real-life European Capital of Culture, has seen their harrowed superhero. Charles Kuddel lives with his “as-normal-as possible” family in Luxusbuerg, seemingly navigating a relatable midlife crisis. There is one thing not so normal about the family: Charles forbids them from eating any lactose, especially Kachkéis. At the start of the film, we find “the Little Duke, Luke” about to be crowned monarch at the equivalent of the Grand Ducal Palace after his father’s tragic accident. When the Little Duke’s crown disappears, the Little Duchy has one person they can turn to: Superjhemp! A now much older Charles Kuddel has to decide his place in helping his country.

Fortunately, the film is also available with English subtitles. Unfortunately, it is not possible at this time to purchase or stream the film online outside of Luxembourg. You can find the DVD of De Superjhemp Retörns in bookstores throughout Luxembourg City.
