 The editor, John Ottman, edited the movie on film. He felt that all the  editing done electronically at the time was horrible because all the good  editors were still working on film (which is much more difficult). Because  of this he thought about putting "Edited on a piece of s*** Steenbeck" at  the end of the credits, but instead settled for the more subtle line  "Edited on film." Tim Robbins was directing Dead Man Walking at the time  and heard about Johns idea, which sparked that films credit ending of  "This film was edited on old machines."
