Behind the scenesEdit
Weyland-Yutani corporation was introduced as the owner of the ship Nostromo in Alien, and the colony in Aliens. Ron Cobb derived the name from the Britsh car manufacturer Leyland and a Japanese neighbor of his named Yutani (湯谷). It's worth noting that the emblem also matches.
Weyland-Yutani also happens to be one of the companies represented by Wolfram & Hart in Angel (as seen in the Episode "Harm's Way").
