Bruce Dern, one of Hollywood's most enduring character actors, has returned to the Cannes Film Festival on Wednesday, over a decade after winning best actor, for the premiere of a documentary dedicated to the 89-year-old's unconventional career path.
Dernsie: The Amazing Life of Bruce Dern is a chronological biographical documentary by filmmaker Mike Mendez about Dern's nearly 70-year career in acting, starting with small bit parts and moving on to create his distinctive acting style, the Dernsie.
A Dernsie is Dern's ability to do or say something not in a screenplay that made his performance unique, born out of advice he received from influential Greek American director Elia Kazan early in his career.
"I never thought I was altogether that interesting, you know what I mean? I mean, I had played the fifth cowboy from the right for 20 years," Dern told Reuters ahead of the premiere.
"He (Kazan) said, 'Since you're going to be slotted in that area, make sure you're the most unique fifth cowboy from the right anybody ever saw and out of that came Dernsie, because you don't write the Dernsies,'" he said.
The film chronicles his relationships and family, featuring interviews with a long list of famous names he has worked with, including Quentin Tarantino, Billy Bob Thornton, Walton Goggins and his daughter, Jurassic Park and Wild at Heart actor Laura Dern.
Dern has been nominated for two Oscars, for 1978's Vietnam war drama Coming Home and road trip movie Nebraska, which also won him the best actor award at Cannes in 2013.
