The first Alien movie, released in 1979, sets this franchise off with a bang. In it, the rag-tag crew of civilians occupying the USCSS Nostromo discovers a derelict ship on an out-of-the-way moon ...

Dallas, who has sole access to Mother as Captain, discovers that their employers, Weyland-Yutani, want the crew to investigate an encrypted signal on a remote moon in the Zeta II Reticuli system.

It turns out that the already frightening Facehugger xenomorph from director Ridley Scott's 1979 sci-fi horror classic "Alien" was actually scaled back a bit from its original design by artist H.R.
