People magazine said Friday that Hollywood stars such as John Travolta and Jennifer Aniston will participate in Winfrey's newest TV creation, "Oprah's Big Give," along with famed athletes such as Andre Agassi and Tony Hawk.
Nate Berkus, a contributor to "The Oprah Magazine," said the new series' focus on traveling the nation helping those in need is the key to its growing celebrity-drawing power.
"Who wouldn't want to be a part of a show whose entire premise is what you can do for other people? I think it's fantastic," Berkus told People.
"Big Give" will premiere March 2 and will feature contestants traveling across the United States helping others and giving away money, all without knowing they could be rewarded for their generosity.
