I only know Paxton, with hindsight, from Titanic and, even less clearly, as one of the young thugs in The Terminator.
Sixty-one is too darn young... :=(
Check out the movie Apollo 13 sometime. I'm kind of a space nerd though, but I think that movie is Ron Howard's best film regardless of my bias on the subject. Paxton plays a fellow astronaut and he gives a pretty damn good performance. One of my favorite things about that movie is that they used actual weightlessness when they filmed many of the space scenes by using a C-130 doing parabolas. I can't imagine being an actor trying to do takes in a plane that is nose diving towards the ground.
Twister is a guilty pleasure of mine, I'll always dig his performance with the late Phillip Seymour Hoffman in that.
I feel like he was a really under-utilized actor but I'm glad there are still a plethora of movies he was in during his time. He will definitely be missed.
