Man, I just vomitted in my mouth while reading through this list… I think it's cool that every one wants to see people who might be able to do the part and all, but aren't a lot of them too old by this point? Besides, Sam Jackson would not make a good ghostbuster. The standard possesed guy role, maybe….
I think the only cast Aykroyd would give his final concent on is one that is made up of kids from his old stomping grounds, SNL. Jimmy Fallon as Pete, Chris Parnell as Ray, Will Ferrell as Egon… and Ernie Hudson as Winston because he hasn't aged a damn day since 1989.
Aside from those guys, the daily show news anchors have a pretty flexiable vibe to them… minus John Stewart… unless it's a cameo.
