Oprah Winfrey is a good friend-- she's willing to lend her star power to friends. Such as when David Oyelowo, who plays Martin Luther King, Jr. in the lauded film Selma, asked her to join the film to lift its profile, she told InStyle on the red carpet at the Film Independent Spirit Awards tonight (Feb. 21).

"I really just wanted to be behind the scenes helping him," Oprah, who was presenting at the awards show, said. "He showed me this tape of himself as MLK, and I thought ''s need a little work. I know everyone else is going to tell you how amazing it is. But I can see him in you.'"

Surely, having Oprah on board has helped catapult Selma to the fore. She explained simply: "I came aboard to do what friends do when they can to try to lift the movie, where at least people would be able to see it."
