after reznor hired peter christopherson of coil to direct the accompanying film to "broken", they developed a friendship. shortly after, reznor asked christopherson to contribute to "fixed". jg thirlwell and butch vig were also recruited for the remixing effort. thirwell's second "wish" remix, "fist fuck", features samples of timothy leary while the final track, "screaming slave", contains various samples of bob flanagan being tortured that were recorded during the filming of the "happiness in slavery" music video. ultimately, vig's contributions were minimal, relegated to the ending passage of "throw this away". about the experience, vig said, "i started recording a lot of new parts, and took it in a much different direction. when it was finished, trent thought the front part of the mix didn't fit the ep, so he just used the ending." reznor, chris vrenna, and james woolley completed many of the remixes in-house.
