Coming to theaters Friday is the 3D thriller "Gravity," starring Sandra Bullock and George Clooney, which is directed by Alfonso Cuaron. The epic film is about astronauts surviving in space after their space shuttle is damaged and they must battle threats like space debris and fires.

But how realistic is the film in portraying what could happen to astronauts in space?

Bullock, for one, worked closely with a female astronaut in developing her character. The film uses space debris, which according to NASA is a huge threat to astronauts and space stations in real life.

IBTimes' Charles Poladian weighs in on the credibility of the film ahead of its release. He was able to get an exclusive interview with astronaut Chris Cassidy, and learned that the most important lesson an astronaut can learn is to be prepared, because anything can happen.

Now we will have to wait and see how the public will respond to the all-star thriller, which aims to make some serious bank at the box office.
