When Hollywood actor Paul Walker died in a car crash in California Saturday, most people only remembered his work on the big screen.

But for some, he was also a man with a big heart in a time of crisis.

When an earthquake ravaged the island nation of Haiti in 2010, Walker didn't act like a movie star, they said.

Walker, one of the stars of the "Fast and Furious" franchise, was just another person trying to make a difference.

"I was just glad he was there. His team was very helpful in moving patients and bringing in other things. They were a great morale booster," said Dr. Paul Berger.

Berger, Dr. Iqbal Sorathia and Dr. Scott Rice, along with more than a dozen members of Life Church in Allentown, worked with Walker at a United Nations earthquake clinic at the Love a Child Mission in Fond Parisien, Haiti.

Walker and a group of California firefighters pitched tents, dug trenches and helped care for patients.

"He was a hands-on type of person. He was not. He did not show that he was a star," said Sorathia.

Sorathia said Walker, after returning home from Haiti, emailed him several times to follow up on the work in Haiti.

WFMZ's Jaccii Farris and Lee Jenkins were also in Haiti with Walker and remembered him working nonstop. When he did pause, it was to try to make a patient smile.

Farris wrote about him as part of 69 News' coverage of the earthquake relief effort.

"There were no cameras following him. I barely got him to pose for a picture for this blog. For Walker, the trip was about one human being helping another," she wrote in her blog.

The doctors said that was very evident by his work ethic in Haiti.

"He was there to work, and I pray for him that God give him a beautiful place in heaven and help and what he did for the people of Haiti. That was admirable and commendable," said Sorathia.

The Haiti earthquake wasn't the only natural disaster to which Walker responded.

When he returned home, he started a foundation, "Reach Out Worldwide," which has helped people in natural disasters all around the world.
