"Dexter's" James Remar stayed in character Friday when he rushed to help an injured homeless man in Los Angeles.

Before playing a deceased detective dad on TV, Remar served as an EMT and he resurrected those skills on Friday when he aided an unidentified homeless man who was bleeding profusely from his head, TMZ reports.

Remar's rep told TMZ that the actor, who dressed the man's wound, performed this good deed out of the kindness of his heart.

But Remar isn't the only A-list name to transform fictional valor into veritable heroism.

In May, Dustin Hoffman saved the life of a jogger, Sam Dempster, who suffered a heart attack in London's Hyde Park, according to The Sun.

The acting legend called emergency services, and stayed by the runner's side until medical technicians came to his rescue.

“I have no memory of what happened," Dempster told the news outlet. "The paramedics told me I had been saved by Dustin Hoffman. It’s unbelievable."
