Trivia: When Weyland is in his office near the beginning of the movie, he's playing with his pen. He starts tapping it on his desk between his fingers, alternating which two fingers he taps between. This is what Bishop does in Aliens (albeit with a knife) with his hand on top of Hudson's; maybe it was programmed into Bishop's intelligence.Michael Westpy
Trivia: There is a dipping bird in the background of the receiving station in Nebraska just like the one in the first Alien movie. Also, the morse code in the background says, "whoever wins. we lose."
Trivia: Just before Miller enters the whaling station on his own, he cracks open a flare. The camera then does a shot behind the door before Miller comes in, but the light cast through the cracks in the door are a carbon copy of "Aliens", when the salvage ship scans Ripley's escape pod with the same effect.
