Our film studio handled the creation of computer effects for a trailer parodying the well-known TV series “La casa de papel.” The film depicts an action scene where there is an exchange of fire between police and robbers. Our task was to add all the elements that must appear in such a scene: bullet impacts, muzzle flashes, smoke, debris, and to mask small mishaps of the production, such as visible cables from pyrotechnics or a shadow of a boom pole.
