Mark Hamill is best known for his portrayal of Luke Skywalker in the original Star Wars trilogy - Star Wars: Episode IV - A New Hope (1977), Star Wars: Episode V - The Empire Strikes Back (1980), and Star Wars: Episode VI - Return of the Jedi (1983) - a role he reprised in Star Wars: Episode VII - The Force Awakens (2015) and Star Wars: The Last Jedi (2017). He also starred and co-starred in the films Corvette Summer (1978), The Big Red One (1980), and Kingsman: The Secret Service (2014). Hamill's extensive voice acting work includes a long-standing role as the Joker, commencing with Batman: The Animated Series (1992).

Hamill was born in Oakland, California, to Virginia Suzanne (Johnson) and William Thomas Hamill, a captain in the United States Navy. He majored in drama at Los Angeles City College and made his acting debut on The Bill Cosby Show (1969). He played a recurring role (Kent Murray) on the soap opera General Hospital (1963) and co-starred on the comedy series The Texas Wheelers (1974).

Released on May 25, 1977, Star Wars: Episode IV - A New Hope (1977) was an enormous unexpected success and made a huge impact on the film industry. Hamill also appeared in The Star Wars Holiday Special (1978) and later starred in the successful sequels Star Wars: Episode V - The Empire Strikes Back (1980), and Star Wars: Episode VI - Return of the Jedi (1983). For both of the sequels, Hamill was honored with the Saturn Award for Best Actor given by the Academy of Science Fiction, Fantasy and Horror Films.

Trivia

Father of Nathan Hamill (born 25 June 1979), Griffin Hamill (born 4 March 1983) and Chelsea Hamill (born 27 July 1988). Nathan was born in the United Kingdom while dad Mark was on location there shooting Star Wars: Episode V - The Empire Strikes Back (1980).
In an ironic counterpoint to his problem of being typecast as a upright hero like Luke Skywalker in live-action roles, he has found that his successful career as an animation voice actor has typecast him as a player of flamboyant villains like The Joker on Batman: The Animated Series (1992).
Attended Nile C. Kinnick High School (known as Yo-Hi) in Yokohama, Japan, where as a senior he played Henry Aldrich in the high school production of Clifford Goldsmith's "What a Life". School is now on the Yokosuka Naval Base in Japan, where it is known by its original name, Kinnick High. Original site of the high school where Hamill acted is now a MyCal department store.
Hamill met his wife, Mary Lou York, when she was his dental hygienist.
He did all his own stunts in Star Wars: Episode VI - Return of the Jedi (1983) -- except two places: where Luke Skywalker jumps off the plank into the Sarlaac, turns, and flips back onto the plank and on the Death Star when Darth Vader throws his lightsaber at the supports of the catwalk. According to "The Making of Return of the Jedi" by John Philip Peecher (c. 1983), his stunt double, Colin Skeaping, performed both of these stunts.
He accidentally hit Peter Stormare during a fight scene in Commander Hamilton (1998).
He did most of his own stunts in Star Wars: Episode V - The Empire Strikes Back (1980), except in the scene in Cloud City where he is sucked out of a window.
He was originally cast as David Bradford on Eight Is Enough (1977), and asked to be released from his contract before Star Wars: Episode IV - A New Hope (1977) came out because he sensed the movie would be successful, and Hamill wanted to focus on his movie career. ABC refused to release him from his contract, thinking that having a successful movie star connected with the show would help "Eight Is Enough" (1977). Hamill was then in a car crash in December 1976 and injured his face. This made him unavailable for shooting the television series, and ABC was forced to recast the role of David, which then went to Grant Goodeve.

Personal Quotes 

I have a sneaking suspicion that if there were a way to make movies without actors, George (Lucas) would do it.
Acting in "Star Wars", I felt like a raisin in a giant fruit salad, and I didn't even know who the cantaloupes were.
"I had the accident way before Star Wars came out, but what really happened has been terribly distorted. I broke my nose, that's it! But I've read accounts about how my face has been reconstructed with plastic surgery and how I was pulling myself along the highway with one arm looking for help. I even heard that I drove off a cliff! That's the best one of all." - Mark Hamill on his auto accident.
The idea of The Force is basically "Religion's Greatest Hits".
You know how there are some stars out there who know how to market themselves? I don't have that.
You know where [the pride] comes from? It's not so much from the industry ... but the 9-year-old kid who looks at you like a cross between Superman and Santa Claus. And you'd have to be a really, really hardened cynic not to be moved by that. Not only that, but just doing the interviews for this animation series, I can't tell you how many people have said, 'I got into the business because of that movie.' ... I totally understand that because I remember walking out of Jason and the Argonauts (1963) and saying, 'I don't know how they got those skeletons to fight, but someday I want that to be my job. To make skeletons fight.'
I never saw myself so much as an actor. I wanted to be a cartoonist like Charles M. Schulz and create my own world and be able to have a studio at home and not commute and be able to be with my family. I just didn't have the skills to pull that off and so I've gravitated toward theater because I like all of it.
