William Thomas Sadler (born April 13, 1950) is an American film and television actor. He's an incredibly prolific character actor who you likely recognize from Die Hard 2, Bill & Ted's Bogus Journey, The Shawshank Redemption, Iron Man 3... hell, throw a stone and you'll hit William Sadler. Whether he's in a leading role or just playing a One-Scene Wonder, his appearance invokes a rise in quality.
He appeared in two episodes of Tales from the Crypt (including its pilot) and both of its film spinoffs. He's also a collaborator with Frank Darabont and Stephen King, having appeared in The Shawshank Redemption, The Green Mile and The Mist. If those two geniuses think Sadler is great, who are you to argue? Huh?
