Dennis Hopper -- stars pay tribute to a legend
"Dennis introduced me to the world of Pop Art and 'lost' films. We rode the highways of America and changed the way movies were made in Hollywood. I was blessed by his passion and friendship," Peter Fonda (pictured, right, with Hopper, left, and Jack Nicholson, middle) tells TMZ. Fonda co-wrote and starred in "Easy Rider" with Hopper in 1969.
