In the upcoming David and Goliath movie, new actor Miles Sloman has been chosen to play the lead role of King David in the film based on the greatest underdog in biblical history.

"When Miles auditioned," said Tim Chey, according to a Charisma News report, "I knew instantly he was the one. This was the young King David who could defeat the giant warrior. He showed a lot of courage on the set even falling off a donkey when the helicopter came too close."

The 22-year-old actor will be playing the role of David, the young shepherd boy who would shock the world when he killed Goliath, the Philistine giant who blasphemed the name of God in front of the Israeli and Philistine army.

David would later become the second King of Israel after the original monarch Saul was killed on the battlefield against the rival Philistine army. David is also famous for being a direct ancestor of Jesus Christ's human nature, when Jesus became mortal in order to die on the cross for the sins of all mankind.

Just like his upcoming role, Sloman overcame all obstacles and was selected among the approximately 4,000 actors who competed for the role of David from cities all over the globe including New York, Los Angeles, Toronto, and London.

"We wanted to find the director, Tim Chey, a phenomenal actor," said Kelly Jacobs, who helped cast the film in LA, "so we casted a wide net around the world."

Chey previously revealed why he wanted to make a film based on the biblical hero.

"I heard a clear voice from the Lord to make this film. I want the audience to really feel the fear of what it meant to take on a 9-foot giant warrior with a sling-shot and what David's incredible faith meant to the world," said Chey in a statement a few months ago, "I'm excited that we can make a Biblically-accurate film about one of the most incredible stories in the Bible. People are already asking me how they can get tickets."

The David and Goliath film is set arrive in movie theaters in March 2015.
