The slime used on the Alien was K-Y jelly.

A sex scene between Dallas and Ripley was scripted, to show how casually the crew would solve long periods of abstinence. Another reference to this was a deleted scene where Ripley inquires with Lambert whether she ever had sex with Ash. The sex scene was ultimately not filmed, but Ridley Scott revived the idea for Prometheus (2012) when Janek asks Vickers if she is a robot, and to prove she wasn't then sleeps with Janek.

Ridley Scott stated that in casting the role of Ripley, it ultimately came down to Sigourney Weaver and Meryl Streep. The two actresses had been college mates at Yale. Ultimately, Weaver was offered the job because Streep was mourning the death of her partner John Cazale at the time of casting.
