Plot hole: When Jackson announces that the symbols are stars, constellations, not words, they immediately go to the room with the device and they have a state-of-the-art map of the universe (which shouldn't even be able to fit on that small map). So they knew it had something to do with travel and the stars. But after two years, couldn't they figure out the star constellations?

Directed by: Roland Emmerich
Starring: Kurt Russell, James Spader, Jaye Davidson, Viveca Lindfors, Alexis Cruz
Factual error: The military ranks for everyone but O'Neil are wrong. O'Neil is a Colonel (Full bird), Kawalsky is wearing the insignia of a Lt Colonel, but is referred to by O'Neil simply as Lt., when he should be called Colonel. All the others are wearing enlisted stripes (Ferretti - TSgt, but is credited as Lieutenant Ferretti), the others are also credited as "Lieutenant", but wearing enlisted stripes.
Colonel Jonathan "Jack" O'Neil: I'm here in case you succeed.
Trivia: The producers, the casting agents, really wanted Jaye Davidson, from "The Crying Game", to play the head bad guy, but Jaye said, "No more movies", so they kept upping the money they would pay him - this is before actors nowadays get phenomenal money - and it was only when they got to a million dollars that he said yes.
