I've read stories on the net which both say that the theatrical cut of Event Horizon is the directors cut.
One source is an interview with a former scriptwriter of AVP, who asked a paramount exec what was in the longer cut of EH as he liked the film. The exec flatly replied back there is no longer cut.
The other source claimed that he saw the final cut with Mr. Anderson and friends at his London home and it was the version seen in theatres. Apparently if anything, Mr Anderson would've made some more cuts to tighten pacing.
