While many remember Species as "that movie with the naked alien babe," hardcore sci-fi fans know it as one of the few films to showcase the mad-genius design work of Swiss artist H.R. Giger. (Not to mention one of the few films that proves the old sci-fi maxim, "sex with alien babe equals gruesome death by tentacle.")

Famously known for dreaming up the Alien who got up close and personal with Sigourney Weaver, Giger also designed Species's Sil (the creepy alien lurking inside Natasha Henstridge) as well as the film's nightmarish ghost train dream sequence. But it was with this sequence that the iconoclast artist (who also created controversial album covers for everyone from The Dead Kennedys to Emerson, Lake & Palmer) began to butt heads with MGM Studio.

Long obsessed with the idea of a "ghost train" (even developing early versions for Alejandro Jodorowsky's aborted version of Dune and Ridley Scott's proposed film The Train), Giger finally got to put his creation to the test during the production of Species. While the studio was adamant about creating the train with cheap computer graphics, Giger dumped $100,000 of his own money into developing a working model locomotive and station. Unfortunately, due to time and budget constraints, Giger's alien skull-and-bones train only appears in the film for a few fleeting seconds.

Years later, Giger again took MGM to task for design changes made in 1998's lackluster Species II and insisted on only being credited with the "original Species design" for future installments. Sorry Sil fans, but that wasn't his design work you saw in 2007's direct-to-DVD fourth-quel Species: The Awakening.

Species airs Wednesday, Mar. 12, at 11PM | 10C. For the full schedule, click here.
