Actor, director and counterculture icon Dennis Hopper, known for roles in such films as Easy Rider (which he co-wrote and directed), Cool Hand Luke, Blue Velvet, True Romance and Speed died today in his home in Venice, California from complications of prostate cancer. He made one of his last public appearances in March, when he was awarded a star on the Hollywood walk of fame. He was extremely frail at the time, but told the crowd, "I just want to thank you, and that's all I can do." Producer Mark Canton once called Hopper "the coolest guy on the planet."
