Harrison Ford and Brendan Fraser are gearing up to show audiences their serious sides.
The pair, who're best known for starring in high grossing family-friendly action flicks, hit the red carpet in Hollywood to screen their new drama Extraordinary Measures.
Joined by John and Aileen Crowley, the couple whose real-life story the film is based around, Brendan explained how "capturing the spirit of the individual" had felt like his biggest challenge.
The film explains how the couple formed their own bio-tech company to try to find a cure for their two children's rare genetic disorder.
Harrison Ford not only stars as scientist Dr Robert Stonehill, he also helped develop the film, for which he's given an executive producer credit.
"It was easy, separate cheques, so not a problem," the actor laughed.
The Indiana Jones star says he hopes audiences will be uplifted by the story.
"I hope people will feel good about the time they've spent in the [movie] theatre. They'll feel positive and they'll have the chance to celebrate their common humanity and feel good about it," he said.
