The two-time Oscar nominee died Saturday after succumbing to his battle with prostate cancer. The funeral took place in Ranchos de Taos, N.M., where Hopper, 74, lived for 12 years following the film Easy Rider, which he directed.
The service lasted two hours in a chapel at the San Francisco de Asis church. A private burial followed the service.
In March, Rider co-star Nicholson attended Hopper's Hollywood Walk of Fame ceremony. "It was a very singular relationship I had with him, like nobody else. We were soul mates in a way. I really miss him," Nicholson said at the funeral.
Hopper's son, Henry Lee Hopper — who read poems from Walt Whitman's Leave of Grass at the funeral — and a few family members also spoke at the service.
