When asked if the movie will ever materialize, Aykroyd had this to say:
“I honestly don’t know. At this point it’s in suspended animation. The studio, the director Ivan Reitman and Harold Ramis feel there must be a way to do it, but Bill Murray will not do the movie. He doesn’t want to be involved. He’s got six kids, houses all over America. He golfs in these tournaments where they pay him to turn up and have a laugh. He’s into this life and living it. I know we’d have a lot of fun [but] I can’t be mad at him. He’s a friend first, a colleague second. We have a deep personal relationship that transcends business and he doesn’t want to know.”You cannot blame Murray for wanting to live his life. This is not exactly the news fans wanted to hear but it is the news we all knew was coming. For further details and the full Dan Aykroyd interview click the source link.
