The film is beloved for its outrageous characters, rapid-fire dialogue, and deep immersion into Brussels' local humor. However, for many viewers—even native French speakers from France—the dialogue can be nearly incomprehensible without (also known as sous-titres français , either for the hard-of-hearing or for European French viewers unfamiliar with Belgian expressions).

Here’s a short write-up about Dikkenek with a focus on the need for French (Canadian/European) subtitles, given the film’s heavy Brussels slang. Dikkenek (2006) is a cult Franco-Belgian comedy directed by Olivier Van Hoofstadt, starring a then-unknown Jérémie Renier, Marion Cotillard, Dominique Pinon, and the unforgettable François Damiens as "Jean-Claude." The title itself comes from a Belgian slang term meaning "a big mouth" or "a show-off."
