Career

Early work

Nicholson as Wilbur Force in The Little Shop of Horrors (1960)

When Nicholson first came to Hollywood, he worked as a gofer for animation legends William Hanna and Joseph Barbera at the MGM cartoon studio. Seeing his talent as an artist, they offered Nicholson a starting level position as an animation artist. However, citing his desire to become an actor, he declined.
He made his film debut in a low-budget teen drama The Cry Baby Killer, in 1958, playing the title role. For the following decade, Nicholson was a frequent collaborator with the film's producer, Roger Corman. Corman directed Nicholson on several occasions, most notably in The Little Shop of Horrors, as masochistic dental patient Wilbur Force, and also in The Raven, The Terror, and The St. Valentine's Day Massacre. He worked frequently with director Monte Hellman as well on low-budget westerns, though two in particular, Ride in the Whirlwind and The Shooting, initially failed to find interest from any US film distributors but gained cult success on the art house circuit in France and were later sold to television.

 Rise to fame

Jack Nicholson as lawyer George Hanson in Easy Rider with Peter Fonda

With his acting career heading nowhere, Nicholson seemed resigned to a career behind the camera as a writer/director. His first real taste of writing success was the LSD-fueled screenplay for 1967's The Trip (directed by Corman), which starred Peter Fonda and Dennis Hopper. Nicholson also co-wrote, with Bob Rafelson, the movie Head, which starred The Monkees. In addition, he also arranged the movie's soundtrack. However, after a spot opened up in Fonda and Hopper's Easy Rider, it led to his first big acting break. Nicholson played hard-drinking lawyer George Hanson, for which he received his first Oscar nomination. The part of Hanson was a lucky break for Nicholson—the role had in fact been written for actor Rip Torn, who was a close friend of screen writer Terry Southern, but Torn withdrew from the project after a bitter argument with the film's director Dennis Hopper, during which the two men almost came to blows.
A Best Actor nomination came the following year for his persona-defining role in Five Easy Pieces (1970). Also that year, he appeared in the movie adaptation of On A Clear Day You Can See Forever, although most of his performance was left on the cutting room floor.
Other Nicholson roles included Hal Ashby's The Last Detail (1973), for which he was awarded Best Actor at the Cannes Film Festival, and the classic Roman Polanski noir thriller, Chinatown (1974). Nicholson was nominated for the Academy Award for Best Actor for both films. Nicholson was friends with the director long before the death of Polanski's wife, Sharon Tate, at the hands of the Manson Family, and supported him in the days following the deaths. After Tate's death, Nicholson began sleeping with a hammer under his pillow,^[ and took breaks from work to attend the Manson trial. It was at Nicholson's home where the rape case for which Polanski was arrested occurred.
He starred in The Who's Tommy (1975), directed by Ken Russell, and Michelangelo Antonioni's The Passenger (1975).
