Late actor Eric Dane is opening up about set drama with actor Josh Duhamel back in 2004 in his posthumous memoir “My Book of Days: A Memoir in Moments.”

“I’m on set, shooting a guest shot for the show ‘Las Vegas,’” Dane wrote according to Entertainment Weekly.

“We’re about to film a fight scene. I ask the lead, Josh Duhamel, to please not grab me by the tie during the scene. He promises me he won’t,” he said, noting that he was dealing with a herniated cervical disc in his neck at the time.

But once the director called “action,” Duhamel pulled on his tie.

“Fire rips through my neck,” Dane explained. “I go, ‘Whoa, whoa, whoa, we have to stop.’ He apologizes, I grunt from the pain, and then, take two. He pulls on my tie again.”

The “Grey’s Anatomy” actor recalled telling the director “You better rein in your boy.” Duhamel apologized to Dane, claiming he “got caught up in the moment.”

But come take three, and Duhamel still hadn’t changed his actions. “Son of a b—-, he grabs my f—— tie again,” he wrote.

Dane continued, “I whip off my suit coat and I say, ‘Let’s go, you p—– ass actor.’”

“I ball my hands into fists and I come at him. Nobody calls ‘Cut,’ the camera keeps rolling, and to the world who sees the whole nasty scene, I’m the aggressor, the hothead, I start the fight.”

Reflecting on the altercation, Dane admitted he regretted how he reacted. “Josh and I have seen each other since and we’re cool,” he wrote, per the outlet. “But I want to say it again. Josh, I was wrong. I should’ve walked away. I’m sorry, dude.”

Dane made a guest appearance as Leo Broder during Season 2 of “Las Vegas,” playing opposite Duhamel’s character, Danny McCoy—a former U.S. Marine and head of security for the fictional resort featured in the series.

Dane died in February at age 53.

His representatives confirmed he passed away from amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, less than a year after he announced his diagnosis.

“He spent his final days surrounded by dear friends, his devoted wife, and his two beautiful daughters, Billie and Georgia, who were the center of his world,” his family said in a statement requesting privacy. “Throughout his journey with ALS, Eric became a passionate advocate for awareness and research, determined to make a difference for others facing the same fight. He will be deeply missed, and lovingly remembered always. Eric adored his fans and is forever grateful for the outpouring of love and support he’s received.”

His memoir “My Book of Days: A Memoir in Moments” is out everywhere where books are sold.
