Richard Patrick (brother of T-1000, Robert Patrick) appears as the police officer in the "Gave Up" segment. Also Robert Patrick can be seen wearing several Nine Inch Nails shirts in the Terminator 2 dvd bonus features.
Apart from the music videos for "Wish" and "Happiness In Slavery" that can be found on Nine Inch Nails' video compilation/documentary Closure (1997), the movie has never seen an official release, mainly due to the fear of the public mistaking the realistic violence for an actual snuff film. The videos for "Help Me I Am In Hell" and "Gave Up" on Closure (1997) were actually not included in the movie, but are alternate versions. It is a common misconception that the entire movie can be found on Closure (1997). Trent Reznor has hinted heavily that the movie will make it's way onto the DVD release of Closure, and clips from it were shown on the official promotional 'Collected' DVD released in May, 2005.
