I really liked Bill Paxton.

Check out Lance Henriksen's twitter/facebook feeds. He shared some private photos from the set of this film with him and Paxton. Much has been made about Paxton being the "only person killed by a Terminator, an Alien, and a predator" but that's actually not true. The other would be Henriksen (a cop killed by the Terminator, Bishop torn in half in Aliens, and a Predator in one of the AVP movies.)
