You have got to be kidding? If you don't know i'll tell you. He was brought in to Aliens as a last minute replacement for an actor who was already doing Hicks, they even have one scene in the movie with that actor shot from the back so you cannot tell, it is the scene where the camera shoots the back of the marines as it's raising revealing the entrance to the hive. With the poor shooting conditions, near death experiences and constant struggles and arguments on set, Micheal Biehn got paid scraps for Aliens. The one photograph showcasing his face, digitized in green scan lines to be shown on the EEV's on board computer revealing the corporal's death, brought in more money for Michael then what he was paid for Aliens and even that was through grinding teeth after fox 1st decided to go with a script where the chest burster erupts from Hicks's body. After this under the table decision reached Michael and he threatened to sue Fox, only then they decided to pay him on bad relationship. Colonial Marines didn't do him any favor as well, i remember 1st day everyone saw Alien 3 in theaters and were saddened by Hicks and Newt's death, now they bring him back and people are pissed of at the decision. If it's like this then this whole thing just needs to end, enough is enough.
