Hollywood's heroic streak continues--this time, with the help of Dustin Hoffman.

Visiting London's Hyde Park last month, the 74-year-old actor encountered a jogger, Sam Dempster, who had collapsed following a heart attack.

Hoffman stayed by the British attorney's side until paramedics arrived.

One of the responders, Martin Macarthur, opened up to British paper The Sun about the importance of the Oscar winner's quick-thinking.

"It is essential to get a history of what happened, and he witnessed the jogger go down," Macarthur explained. "He was the main witness and saw him stagger and go down. He stayed on the scene for the whole duration of the resuscitation which was about 15 minutes."

Added the paramedic, "[Hoffman] was very concerned . . . When we were carrying the patient into the ambulance, he said 'Great job, guys.'"

After undergoing surgery, Dempster is expected to make a full recovery. "I have no memory of what happened," he admitted to the paper. "The paramedics told me I had been saved by Dustin Hoffman. It's unbelievable."
