Humphreys' enlistment ends June 4 and Hollywood is already calling. He's landed a role in an independent film, playing, of course, a soldier.
It's a route similar to that of Tom Hanks, who won the Oscar for playing adult Forrest Gump.
Hanks later starred in "Saving Private Ryan" and produced "Band of Brothers," a series about the men of Easy Company of the 506th Parachute Infantry Regiment during World War II.
"I guess I'm following in his tracks," Humphreys said.
The film is called "Pathfinders," the story of the men of the 504th Parachute Regiment who jumped into Normandy early on D-Day to disrupt German activities and find the way for the coming invasion force. He heads to Oregon later this year for filming, playing the part of Eddie Livingston, one of the original pathfinders.
"It's a small start. I'm still going to go to school at the University of North Alabama, but if (acting) snowballs and it goes somewhere else, that'd be fine," he said.
Humphreys said making "Forrest Gump" was a great experience and he fondly remembers Hanks and Sally Field, who played his mother.
"Both of them were excellent people, just like you would expect them to be," he said.
He was especially excited to work with director Robert Zemeckis. Humphreys said he was familiar with Zemeckis' other works, including the "Back to the Future" trilogy.
"I tried to get him to do a fourth," Humphreys said.
He recalled that during filming he and Hanks worked closely to match the boy's running style and accent. Humphreys has since lost most of his distinctive Southern drawl but maintains the boyish looks, right down to the cropped Army haircut and lean body. His face looks a bit older, but doesn't appear to need to shave daily.
Humphreys said he chose not to chase an acting career as a child because he liked school and was content to continue growing up in the South, even though his parents would have backed him. There were offers, but until now, the only ones he took were in high school productions.
