Alien Easter Egg - All in the Family

When entering the alien vessel, looking for the source of the SOS signal, the Nostromo's crew comes face to face with the huge remains of the vessel's alien navigator still sitting in his chair. In one take, the crew is dwarfed by its size. The actors used in this scene are actually children (Ridley Scott's), dressed up as astronauts. By doing so Scott could make the set look larger than life.
