Trivia: I recently watched "Event Horizon," essentially a 1997 B-movie sci-fi flick with some A-list cast members such as pre-Matrix Laurence Fishburne and Sam Neil. I knew the movie was in trouble the moment they started to remove their helmets on the derelict ship (sound familiar?) without a proper check.
That was handwaved earlier in the script, when they were scanning the ship:
"Pressure?"
"The hull's intact, but there's no gravity, and thermal units are off-line."
Far bigger problems are people smoking in space, and Sam Neill explaining wormhole theory to ASTRONAUTS as though they are pre-schoolers.
I've long fantasised about making a "corrected" edit of Event Horizon which would minimise these problems and make more sense of the ending.
It's a terrific-looking film with some unique ideas, even if those ideas are not exactly scientific.
Definitely better than Prometheus.
