Sidney Berthier is a filmmaker whose work spans narrative film, broadcast television, and branded storytelling. He trained in film at the University of Warwick and completed a Masters at the University of Cambridge. His practice combines directing, editing, and cinematography, with a focus on character-driven storytelling and cinematic form.

Born in Paris, France, Sidney Berthier graduated with a Baccalauréat at the age of 15, two years ahead of the usual age for high school students. Passionate about cinema since childhood, he was then accepted into the University of Warwick at the age of 16 to study Film and Television within the department co-founded by V.F. Perkins. Keen to pursue his passion, Sidney then moved to the University of Cambridge at the age of 19, making him one of the youngest students ever to undertake a Masters degree.

Some of his research on James Bond which dealt with David Bordwell's concept of "intensified continuity" editing and Svetlana Boym's notion of "restorative" nostalgia was also published in the British Guild of Film and TV Editors magazine.
