Ghostbusters director Ivan Reitman is considering returning to direct the long-awaited third installment of the spooky movie franchise.

Original stars Billy Murray, Dan Aykroyd, Harold Ramis and Ernie Hudson are returning to the big screen for a second sequel - a full 20 years after Ghostbusters 2.

Reitman, who directed the first two films, has been offered the chance to complete the trilogy - but is waiting until he reads the script before he commits.

He tells MTV News, "I've never ruled (directing it) out. I certainly was responsible in every capacity for the first two movies so I certainly wouldn't wander away from the third one - especially if it's something we all think is worth doing.

"The script is going to be turned in a month or so and we'll see. All the casting and directing speculation is really just speculation."
