The film's title itself is a joke, as there is no "Brice de Nice 2".
The full movie was first released on youtube: it was another joke. After 3 minutes the "movie" stops to reveal Brice in a white room with very little furnitures (beginning isn't the real one). The static shot lasts 80 minutes with the character poking fun of us, urging us to see the movie in theaters, and most of the time sleeping on the couch or moving around a little.
This sequel was released 11 years after the first movie.
