Funny thing about the aliens movie is that the chick that played Vasquez show up in mini skirt and high heals, trying to look like some hot Latina. She thought the movie Aliens was about immigration.
"Goldstein didn't have an agent, that was all the information that she had to go on. While she had seen the film "Alien," she did not know that they were doing a sequel, so she figured that it was for a film about immigration. She told Starlog:
“I had seen Alien, but I had no idea this was a sequel. It had been so long ago, it didn’t even occur to me. I thought it was about actual aliens, you know, immigrants to a country. I was wondering why they wanted Americans. I figured the movie was about lots of different immigrants to England.”
So she showed up at the audition wearing "high heels and lots of makeup, and I had waist-length hair." She figured out that something was way off when everyone else was wearing army fatigues. It was when she went in read and saw posters for "The Terminator" that she knew that she was really in trouble. In a brilliant twist of fate, though, the nice blouse that she was wearing happened to be sleeveless, which showed off Goldstein's arms. She had taken up bodybuilding recently and it showed in her arms.
She later recalled, "'She said, ‘Are you an actress or a bodybuilder?’” Goldstein laughs. “I was a gymnast. I just happened to be in the best shape of my life.'"
So they agreed to see her again, only this time she wore army boots and pulled her hair back and everything and eventually, she got the role.
