George Clooney Replaced Robert Downey Jr. in ‘Gravity’
Director Alfonso Cuaron originally offered Robert Downey Jr the lead role in the film ‘Gravity’ because he was well aware of his impressive Hollywood resume and knew he could do it. But when the cameras started rolling, Cuaron realized that he had made a mistake. It’s not to say that Downey wasn’t a great actor. He just wasn’t the right fit for the role. So, the director started looking again and eventually found George Clooney, who did a great job.
