Caution, there are spoilers about the movie if you have not watched it yet!
At the end of Prometheus the robot David spoke to the Engineer in an alien language without subtitles for the audience to understand. It was one of the many puzzles from the film that theater goers were left with.
The words caused the Engineer to tear David’s head off and beat Weyland to death with it.

According to Dr. Anil Biltoo of the SOAS Language Centre in London who served as the Linguist Teacher on the film, here’s the translation:
“This man is here because he does not want to die. He believes you can give him more life.”
