Castel would continue to appear in a number of Rollin's films, such as, the comedy, Tout le monde il en a deux, and one of his most successful works, Lèvres de sang, which starred Jean-Loup Philippe and Annie Belle. Castel accepted work in several of Rollin's pornographic films, when the director was facing financial difficulty at the time while trying to make up the budget for his intended projects, turning to the adult film industry as a viable option; featuring in Phantasmes, Douces pénétrations, Introductions and in her final collaboration with Rollin, Suce moi vampire, which was an extended pornographic version of Lèvres de sang, with the hardcore scenes shot and inserted into the film in 1976.
