If you liked Event Horizon, you'll love Pandorum.
You've probably already seen it, but Interstellar is excellent spaciness and deals with a lot of scientifically proportionate spectacles. The modeling of the supermassive black hole in the film was done by astrophysicists who ended up publishing a paper based on that experience.
The 2004 reboot miniseries of Battlestar Galactica is pretty great, and includes some delicious space dogfighting.
The Fifth Element is always a classic.
Starship Troopers for that Star Marine FPS hype.
Blade Runner is a legendary film. Doesn't take place in space, but does takes place during a time when humanity is an advanced space-faring civilization.
Alternatively, if you're like me and you've seen too many films and they don't make new ones fast enough, I recommend the 2004 Battlestar Galactica series (which spawned after the success of the miniseries, and which you'll undoubtedly want to watch after finishing the miniseries anyway), Stargate SG-1, and any of the Star Trek series (i'm enjoying Voyager currently).
