 The scene where Jason Issacs character D.J. is found by Laurence  Fishburne hanging in the air with his chest cut open ran much longer  with D.J.s guts hanging out of him and some of it laying on the  table. Paul Anderson used a mylar mirror on the operating table  simulate the effect with Issacs actually hanging on wires. This can  be seen in the DVDs Making of Event Horizion documentary.
