Dennis Hopper has died at the age of 74 due to complications from prostate cancer. The actor best known for his roles as manic, narcotic enthusiasts started his career playing tamer characters. He starred as the son of wealthy rancher Rock Hudson in Giant, and a convict in Paul Newman's corner in Cool Hand Luke.

It was his turn as a hippie biker in Easy Rider, a hippie journalist in Apocalypse Now, and oxygen-sucking Frank Booth in Blue Velvet that made us all realize what Hopper was preparing for his entire career -- blowing up Keanu Reeves in Speed. Or playing King Koopa in Super Mario Bros. I get those two roles mixed up. Either way, let's hope he's at the pearly gates right now giving St. Peter a pop quiz. Hot shot.

You'll be missed, Mr. Hopper.
