Dennis Hopper Dies

Dennis Hopper, who lit up the silver screen in films such as 'Easy Rider,' 'Blue Velvet' and 'Speed,'  has passed away. He was 74.

Sam Maydew, a rep for Hopper, tells ET the star died of complications from prostate cancer in Venice, Calif. on Saturday morning, at home and surrounded by family and friends.

The actor's prostate cancer diagnosis was announced in October 2009, and his condition had been on the decline in recent months. Unable to be treated with chemotherapy, he allowed the disease to run its course.
