George Clooney Wrote Key 'Gravity' Scene According To Alfonso Cuaron

Warning: Spoilers ahead about a key moment in "Gravity."

One of the most important scenes in "Gravity" was written by none other than the film's star, George Clooney.

In an interview with Vulture, "Gravity" director Alfonso Cuaron revealed that Clooney was responsible for a key moment in the film, when his deceased astronaut, Matt Kowalski, comes to Sandra Bullock's main character, Ryan Stone, in a dream.

"We were struggling with rewrites, we'd stripped everything, a lot of the dialogue; we knew that anything that was going to be said, it was going to have a lot of weight. There was one scene we were doing over and over and over, and George overheard that we were dealing with that," Cuaron recalled. "And then one night I receive an e-mail from him, saying, I heard you were struggling with this. I took a shot with the scene, Read it. Throw it out. And we ended up using it. This was exactly what we needed."

The moment, which leads into a sequence where Stone, now awake, discusses her daughter in a prayer said to Kowalski, is one of the most controversial in "Gravity," a fact made clear by some comments on the Vulture piece.

"So he admits that the weakest scene in the movie came from Clooney?" noted one commenter. "That Clooney's character re-appearing was something Clooney re-wrote himself? That scene was the only thing, literally the only thing, that kept the movie from being essentially perfect in my eyes."
