Alien Nation is a 1988 American science fiction action film directed by Graham Baker. The ensemble cast features James Caan, Mandy Patinkin and Terence Stamp. The film depicts the assimilation of the Newcomers, an alien race settling in Los Angeles, much to the dismay of the local population. The plot integrates the buddy cop film genre with a science fiction theme, centering on a union between a veteran police detective Matthew Sykes (Caan) and Sam "George" Francisco (Patinkin), the first Newcomer detective. Sykes and Francisco probe the criminal underworld of the Newcomers as they attempt to solve a homicide. Wikipedia
Det. Sgt. Matthew Sykes: What is it?
Det. Samuel 'George' Francisco: Nothing.
Det. Sgt. Matthew Sykes: Come on, it's not nothing! When you talked to that coroner with that request it looked like you were about to shit peach pits... and it's not nothing now! Don't lie to me, George, you're real bad at it. That slag in there didn't die from just bullet wounds, am I right? Am I right? Tell me! You tell me and you tell me now. NOW!
Det. Samuel 'George' Francisco: The drug is called ja-bru-kha. It is a potent narcotic!
Det. Sgt. Matthew Sykes: How potent?
Det. Samuel 'George' Francisco: More potent than any human drug you can imagine. The controllers regulated it, we would receive small amounts for our work in the mines.
Det. Sgt. Matthew Sykes: You? You were on this shit?
Det. Samuel 'George' Francisco: Yes! We all were! We were engineered as slave laborers. It was our only means of pleasure allowed! The harder you worked the more you got, the more you got the harder you worked. Thousands of my people died, I lost my best friend. It is a nightmare! I will not let it happen again.
Det. Sgt. Matthew Sykes: Ok. You know, it was simple... I mean, all you had to do is tell me. I mean, why couldn't you let me know?
Det. Samuel 'George' Francisco: Your people don't know about this part of our past and they cannot know it, it would threaten our entire existence here.
