Forget him.....He's gone!

Okay if your a fan of the franchise you may know of these but if not here some actors who were supposed to be in the Alien movies but for one reason or another had to be replaced.

Jon Finch as Kane

Early on in the shooting of Alien Jon finch was cast as the part of Kane however as the shooting went on the poor guy got sicker and sicker. Well into the shooting Scott decided that for the sake of the actors health he couldn't remain on set in his condition so the part was recast with John Hurt.

James Remar as Hicks

The Dexter star was cast as Hicks and one has to wonder would he have been the soft Spoken marine we all know and love today. Well we'll never know because Remar at the time had issue with substance abuse and even blew the roof off the set with a shotgun at which point big Jim had to show him the door and in stepped Michael Biehn.
