Program Note: Watch the full interview with Harrison Ford on CNN's "Your $$$$$," Saturday at 1 p.m. and Sunday at 3 p.m ET.
He didn't bring a bullwhip or a fedora, but Harrison Ford brought his star power to a cause close to his heart: climate change.

Ford joined the president of Guyana and executives of Starbucks, SC Johnson, Wal-Mart, Harrah's, Wrigley, Conservation International and others to launch Team Earth, a "global sustainability movement."
Think of it as the companies, environmentalists and politicians together trying to outrun the massive rolling boulder that is climate change.
"You have to create a movement," Ford told me, after a Team Earth press conference in Manhattan. "Like the civil rights movement, like the anti-war movement, like the youth movement of the 60's. If we can come together as an efficient mass, the issues will be addressed."
Ford is particularly concerned about deforestation and notes that more than 20 percent of greenhouse gas emissions are because of destruction of the rainforests.
Ford spoke on the eve of a climate change summit at the United Nations, where the presidents of the two largest greenhouse gas emitters – the U.S. and China – will address the world on the issue. In Pittsburgh later this week, leaders will negotiate a framework for addressing climate change ahead of a critical summit in Copenhagen in December.
It's a lot of politics and process and, well, talking. Environmentalists like Ford are trying to seize on the momentum heading to Copenhagen.
"We have two months to drive one million people to teamearth.com and get a million people to sign up to this to become member of Team Earth. We are already all members, we just need to get off the bench and get into the game. So I think that will have a very effective, it will be a very effective platform."
Celebrities often have their pet causes or public politics and sometimes lack credibility on their subjects. Ford boasts legitimate green cred. A longstanding Conservation International board member, he grudgingly switches to questions about Ford the actor, after a long discussion about Ford the activist.
Any chance for a fifth Indiana Jones movie? At this point, he has been playing the globe-trotting archeologist longer than some of his fans have been alive.
"I've got a couple of projects coming out of next year. A project I am probably going to start at the beginning of the year and if there's a good script for Indy, I'd be happy to do it."
