Garner's showbiz career started in theatre, according to Variety. After cueing gigs for Broadway shows such as "The Caine Mutiny Court Martial," Garner scored a nonspeaking role in the production. He studied the play's star, Henry Fonda, and went on to get a bigger role in 1954 for a play entitled "Caine."

In 1955, Garner earned part on the Warner Bros. TV series "Cheyenne." Garner starred alongside Marlon Brando in "Sayonara," and had a supporting role in "Darby's Rangers."

The big break of Garner's career was when he starred as Bret Maverick in the 1950's TV series "Maverick." He was part of the show for 10 years, and the wise-cracking role gave him a Golden Globe in 1958 for most promising male newcomer, as well as an Emmy nomination in 1959.

Garner went on to appear in films like "Boys' Night Out," "The Great Escape," " The Thrill of It All," "Move Over Darling" and "Hour of the Gun." He also starred in "The Rockford Files" from 1974-1980 and won an Emmy for his role on the show in 1977.

Throughout the years, Garner continued to work consistently and appeared in hits such as "The Notebook," where he played Ryan Gosling's older version. James Garner was also a recipient of the Actor's Life Achievement Award in 2005.
