In this emotional medical drama, Brendan and Keri are a couple whose two children are fighting a rare and fatal genetic disorder. Together, they search for a researcher -- played by Harrison -- to find a cure.

CBS Films announced last month that due to an overwhelmingly positive response from test audiences, they are moving up the release date for 'Extraordinary Measures' from spring to January 22, 2010, making the film the studio's first release.

Earlier this year, ET visited the set in Portland, Oregon. This moving drama is inspired by the true story of John Crowley, a man who defied conventional wisdom and great odds, and risked his family's future to pursue a cure for his children's life-threatening disease.

"This is an extraordinary story of a guy who went against all odds," Harrison told ET. "I thought it was a sort of opportunity to tell an uplifting kind of story about very courageous people."

"What parent wouldn't do anything for their kids?" Brendan asked. "This is the crowning example of an individual who just would not take no for an answer. He was not a scientist by any means, but he found one who was a bit of a renegade for sure -- but brilliant."

"This isn't going to be a sad story," added Keri Russell, who plays Fraser's wife in the film. "This is a story about people who are surviving this, and these are really extraordinary people."

"The personal part of the Crowleys is an important part of the story," said Harrison of the film's real-life inspiration. "He's a remarkable guy, he's a remarkable intellect, he's a compassionate, wise fella -- and fun at a party."
