Sad news. One of the better character actors who was also strong enough to become a leading man in Hollywood.
I cannot remember for the life of me any real stinkers that he was in. Some of his movies, like "Twister", may have been mindless popcorn summer blockbuster type of movies, but at least they were entertaining.
I've mentioned it before on here, but one of my all-time favorite Bill Paxton movies is an underrated, little known gem of a psychological thriller called "Frailty". Holy sh!t is that a good movie. Also starred Matthew McConaughey and one of his "Tombstone" co-stars, Powers Boothe. It might be hard to find, but by all means make the effort to find it.
