Aykroyd: 'Ghostbusters' is go

Dan Aykroyd has confirmed the third 'Ghostbusters' movie is all set to go before the cameras - with the original cast in place to reprise the characters from the 1984 film.

The movie star reveals Sigourney Weaver has signed on for the project, alongside himself, Bill Murray, Harold Ramis and Ernie Hudson - and the film could start shooting this winter.
