Aykroyd plays Dr. Raymond Stantz, a parapsychologist turned ghostbuster who, along with his compatriots Dr. Peter Venkman and Dr. Egon Spengler, works to rid Manhattan of ghosts and poltergeists in Ghostbusters, directed by Ivan Reitman. Co-starring Bill Murray, Sigourney Weaver, Rick Moranis, Harold Ramis, and Ernie Hudson.
I believe that 50% of Ghostbusters’ success is due to Sigourney, Moranis, Ramis and my writing and Reitman’s direction. And 50% was Murray and his presence as a leading man – he’s the greatest. He just brings such great energy and creativity and he brings the audience because they love that kind of hung dog who had such vulnerability. Really, I owe a lot to Billy.
