One of the more familiar faces on television and in film for over two decades, William Sadler was a versatile character actor whose granite features and gravely voice led to roles as tough guys and authority figures in films ranging from "Die Hard 2" (1990), "The Shawshank Redemption" (1994), "The Green Mile" (1999) and series like "Roswell" (The WB/UPN, 1999-2002). A veteran of the New York stage in the 1970s and 1980s, he segued into film in the mid-1980s and found steady work as cops, detectives and a rogues' gallery of heels in the aforementioned projects. When given the chance, Sadler also displayed a wicked knack for absurd humor, as his turn as the Grim Reaper in "Bill and Ted's Bogus Journey" (1991) proved beyond a shadow of a doubt. In the 1990s, Sadler was seen mostly on television, but returned frequently to features for small but memorable parts in "Kinsey" (2005) and "The Mist" (2007). His broad spectrum of talent and believability in every role he played made him one of the most dependable character actors in the business.
