Walker stars in the upcoming Hurricane Katrina drama "Hours," which Lionsgate's Pantelion Films is to release December 13. He also stars in "Brick Mansions," a remake of the French action film "District B13" in post-production that Relativity plans to release next year. "Paul was an incredibly talent artist, devoted philanthropist and friend," Relativity President Tucker Tooley said in a statement.
He formed Reach Out Worldwide in 2010 to aid people struck by natural disasters.
A friend of Walker's who attended the fundraiser Saturday, Bill Townsend, told AP Radio, "He was very happy. He was smiling at everybody, just tickled that all these people came out to support this charity. He was doing what he loved. He was surrounded by friends, surrounded by cars."
Walker is survived by his 15-year-old daughter.
