Alfonso Cuaron explained why Robert Downey Jr. was not correct for "Gravity."

In an interview with the Huffington Post Cuaron revealed that Downey Jr.'s style of acting would not work with his movie. He stated, "Downey was attached. But we just kept on extending the process. And also it was very clear that the technology we were going to use -- it was not the most compatible thing for what Robert is the best at. That is, he takes one scene and he just starts riffing. And because of the technology that we use, it's pretty much limited. We have to pre-program the film before shooting."

Cuaron also suggested that the actor's schedule was too busy and that it was taking way too long to get the film made. He said, "We were blessed because a lot of people wanted to do this thing. And people that we talked about and we had conversations -- and with all of this now you have a 15 minute conversation to catch up and say hello to someone about one project and suddenly, it's announced. Everything is announced as things are happening."

The director also spoke about working with Sandra Bullock and Geroge Clooney and said, "Well, as long as we could feed it in the context of timing and physical positioning of everything, OK. But if not? Sorry, dude. But that's the thing, both George and Sandra, we had endless conversations before. We animated the whole film before. We could have released an animated version with the voices of Sandra Bullock and George Clooney. We watched it and we gave suggestions and if they had notes or ideas, then it was just about programming the whole thing. it was amazing because, yes, they changed quite a lot, relatively speaking. But it was always in the context of what was there already."

"Gravity" is Cuaron's first film since 2006's "Children of Men." He is best known for his work on "Y Mama Tambien" and "Harry and the Prisoner of Azkaban."

"Gravity" will open the Venice Film Festival at the end of August and will be released in theaters by Warner Bros on October 4.
