A movie by Lukas Bossuyt

After studying civil engineering, Lukas Bossuyt decided to go to London. Three years later, he obtained his degree of filmmaker at the London Film School. After that, he made his name as an advertising director, and built a career as a scriptwriter for Flemish television series such as: Aspe and De Rodenburgs. In addition, Lukas wrote and directed two short movies: Strawberry Flavour and Elisabeth. For his first feature film, Sum of Histories, he was also the writer and director.

Leuven & KU Leuven

The film crew of Sum of Histories settled on different, recognizable locations in the city of Leuven, the setting for the movie. One of the central locations is the Arenberg Castle and the surrounding park. The castle was donated to the KU Leuven in 1916 by the Duke of Arenberg, and is today the School of Engineering. It is the ideal setting for a scientific experiment. Other well-known locations are the State Building and the City Cemetery. Or maybe you, just like the characters, have already visited the catchy Italian bar Zoff or the bar 'De Blauwe Kater'. When you walk on 'de Grote Markt' or the Henri Regastreet, you’ll join the footsteps of the actors of Sum of Histories.
