John James revealed he took "method acting" to a "new level" after he was rushed to the hospital while in Serbia filming for the upcoming Hunter Biden biopic.

James, 65, took a tumble Saturday at a top Belgrade restaurant while he was off-set. The incident resulted in a head injury. 

The actor, who is portraying President Joe Biden in "My Son Hunter," pointed to "method acting" as the reason for his injury.

"I've been playing stumbling and bumbling Joe Biden for almost a month now on set, I guess I took method acting to a new level. I was walking into a Belgrade restaurant, and I collided with the side of a glass door," James said.

"I had a large cut above my eye, and there was a lot of blood on the sidewalk. I was pretty stunned and was rushed to a hospital," he added.

The Serbian hospital was packed, but gave "top class treatment," according to James.

"It was Saturday night in the Belgrade ER room, and like Saturday night ERs all over the world, it was pretty crazy, but I received top class treatment and a couple of stitches and will be back on the set on Monday," he said. "The show must go on."

"The script has it all," James continued. "Money, power, greed, sex, drugs and alcohol. That kind of reminds me of ‘Dynasty.’ Anyway, I hope you get a chance to watch our movie. I know you’ll enjoy it."

"My Son Hunter" will explore Hunter’s "dodgy business dealings, party/strip club lifestyle and addiction struggles," noted a press release sent to Fox News.
