Below is a little information about him which I took from Wikipedia. He will truly be missed.
He was unable to build on his success for several years, until a featured role in Apocalypse Now (1979) brought him attention. He subsequently appeared in Rumble Fish (1983) and The Osterman Weekend (1983), and received critical recognition for his work in Blue Velvet and Hoosiers, with the latter film gaining him an Academy Award nomination for Best Supporting Actor. He directed Colors (1988), and played the villain in Speed (1994). Hopper's later work included a leading role in the television series Crash.”
