El maníaco invisible

The film is primarily regarded for being one of the few non-pornographic works starring lead actress Shannon Wilsey (who later took on the name Savannah). The film's reception had a profoundly negative impact on the actress. Despite the fact that it was well received for its comedic merits, she felt mortified about her performance. In an interview for the E! True Hollywood Story documentary on the life of the actress, former boyfriend Billy Sheehan recounted how Wilsey was utterly humiliated during the film's premiere. Whenever the audience would laugh at one of her lines she could not differentiate whether they were laughing at her personally or the character. The experience forever marred Wilsey on a personal level and she soon afterwards resigned herself to pursue a career exclusively in the adult entertainment industry.
