A jogger who suffered a cardiac arrest was saved after Hollywood veteran Dustin Hoffman went to his aid.
Sam Dempster, 27, collapsed during a run in London's Hyde Park on April 27.
Dustin, who has a house in the capital, was enjoying a morning walk when he saw Mr Dempster crash to the floor, landing on his face.
When paramedics from London Ambulance Service (LAS) arrived the Rain Man star explained what happened.
The 74-year-old actor waited with the stricken lawyer until he was resuscitated and rushed to hospital. When it became clear the patient was stabilised Dustin congratulated the three ambulance crews present saying: "Great job, guys."
Paramedic Martin Macarthur, who saved Mr Dempster with colleague Luke Sullivan, said: "As we got out of the ambulance Dustin Hoffman explained what had happened.
"It is essential to get a history of what has happened and he witnessed the jogger go down, 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. He was very concerned.
"And at the end Mr Hoffman was kind enough to come up to all the crews and said, 'Great job, guys', which was really nice of him to say."
Writing on his recovery blog "Heart-throbbing", Mr Dempster applauded the actor and the paramedics. He said he was "indebted" to Dustin who was his "new-found favourite celebrity".
