Hollywood Marine veteran Rob Riggle doubts modern stars would make Jimmy Stewart's WWII sacrifice

Hollywood Marine veteran Rob Riggle has doubts about whether today's stars would be willing to step away from the spotlight to serve in uniform like WWII bomber pilot Jimmy Stewart.

Stewart famously walked away from an Oscar-winning career at its peak to enlist in the U.S.

Army Air Corps as a private nine months before the attack on Pearl Harbor.

In the upcoming biopic "Jimmy," Riggle, who is a retired U.S.

Marine officer, plays Colonel Terrill, Stewart's squadron commander and mentor.

"I would be surprised if anybody made that same choice today, especially an actor of his status," Riggle said.

"You got to remember, he won an Academy Award before the war," "The Hangover" star continued.

"It wasn't like he was an up-and-coming actor.

He was an established Academy Award-winning actor before the war.

And then decided to put on the uniform and not in a safe way." "He wanted to put on the uniform and serve where he could be used best," Riggle added.

"And he was a pilot, so he put his hand in the air and went into harm's way.

And I don't know if you'd see that today.

I mean, I hope you would, but I would be surprised." Stewart joined the military in March 1941, just 28 days after winning the best actor Academy Award for his performance in the classic 1940 film, "The Philadelphia Story." He had tried to enlist in late 1940 prior to winning his Oscar but was initially rejected for being five pounds under the weight requirement for his 6'3" frame.
