Mark Hamill Shares Embarrassing First 'Star Wars' Screen Test with Harrison Ford: 'We Never Did Talk About It Later'

Actor Mark Hamill, best known for playing Luke Skywalker in the Star Wars films, on Sunday shared an embarrassing old video of his first ever screen test with co-star Harrison Ford.

CNBC contributor Carl Quintanilla first shared the clip to Twitter on Saturday, tweeting to Hamill's account and asking the actor if he could "share any color" on the footage.

On Sunday afternoon, Hamill — who has previously shared illuminating tidbits of information about the classic sci-fi films — retweeted the video with some of that requested background color.

"My screen-test for @starwars w/ Harrison on the 1st day I ever met him. Neither 1 of us had read the script at this point, only this 1 scene. I asked George what kind of movie it was — 'Let's just do it, we'll talk about that later.' We never did talk about it later — we just did it," the 67-year-old actor wrote.

"Mark, you rock," Quintanilla replied.

In the nearly two-minute black-and-white clip, a young Hamill and Ford, who played the iconic Han Solo, can be seen going over some lines about the destruction of Alderaan — while dressed in casual attire, rather than the costumes they would soon make part of movie history. Although it's unclear exactly when the screen test was shot, Star Wars: A New Hope, the first film of the epic franchise, was released on May 25, 1977.

Hamill's assertion that neither him nor Ford had read the script for the film before rehearsing the scene in the clip sets the viewer up for disappointment. Ford's performance in the screen test demonstrates that the actor had already captured Solo's cocky attitude before reading the script, while Hamill's portrayal of Skywalker seemed far more aimless.

[SPOILERS AHEAD FOR RECENT AND UPCOMING STAR WARS FILMS]

While Hamill's Luke Skywalker appeared to pass away in Star Wars: The Last Jedi, the actor will return to reprise the role one more time in the upcoming Star Wars: The Rise of Skywalker as a force ghost, similar to Obi Wan's return in previous films.

Three years after her unexpected death, Carrie Fisher, who played Princess Leia in the original trilogy, will also appear in The Rise of Skywalker as General Leia Organa. Earlier this year, director J.J. Abrams confirmed that the upcoming film will include unused scenes featuring Fisher from Star Wars: The Force Awakens. When asked how his team has managed to fill the void that Fisher left behind, Abrams said "we couldn't."

"We all talked about how to move on. She was the best, she was glorious, she was amazing," he added. "We all just loved her. It was impossible, there was no way. You don't recast that part, and you don't have her disappear. Using CGI was out of the question."

Star Wars: The Rise of Skywalker will be released to theaters in the U.S. on December 20, 2019.
