Alien movie costume from James Cameron's Aliens...

James Cameron's Aliens is one of my all time favourite sci-fi action movies and probably one of the best sequels ever made.

The 1986 movie has suspense, horror, space marines, explosions, face huggers, chest bursters, the Alien Queen and an iconic heroine with a big gun who's not afraid to use it. In the original
Ridley Scott
helmed space classic, 'Ellen Ripley' (Sigourney Weaver) only faced one Alien, in the sequel she has to face a whole army of the deadly creatures.

Giger inspired Alien is such a creature design classic, I was totally thrilled to see this original Alien body suit used in Aliens on display at the AFI movie villain costume showcase at Disney's Hollywood Studios on September 22, 2010, courtesy of Planet Hollywood Inc.

The costume is amazingly detailed when you see it up close, from its skeletal-like frame to its spiny tale, and you can just imagine it dripping with slime as it chases Ripley and her ragtag group of survivors through the air vents of the colony on planet LV-426.

On screen you totally forget there's a man inside the creature body-suit.

Now this would make a truly scary costume to wear for Halloween.
