Apparently so, according to Coming Soon:
After years of rumors, it appears that Ghostbuster 3 is finally moving forward and will likely do so with or without Bill Murray's involvement. Dan Aykroyd appeared on The Dennis Miller Show to discuss the project, dropping specific details about the sequel, hinting that the plan is to film in Spring of 2012 no matter what happens casting-wise.
"Yes, we will be doing the movie and hopefully with Mr. Murray," he says, "That is our hope. We have an excellent script. What we have to remember is that 'Ghostbusters' is bigger than any one component, although Billy was absolutely the lead and contributive to it in a massive way, as was the director and Harold [Ramis], myself and Sigourney [Weaver]. The concept is much larger than any individual role and the promise of 'Ghostbusters 3' is that we get to hand the equipment and the franchise down to new blood."
The comedian also confirmed reports that the plot will revolve around a new generation of Ghostbusters and hinted at the states of his and Ramis' characters.
"My character, Ray, is now blind in one eye and can't drive the cadillac," he says, "He's got a bad knee and can't carry the packs... Egon is too large to get into the harness. We need young blood and that's the promise. We're gonna hand it to a new generation."
As for who might be cast as the new characters, Aykroyd says that, while no decision has been made, he does have a fondness for one piece of prospective casting.
"I like this guy Matthew Gray Gubler from the 'Criminal Minds' show," he adds, "But there's going to be a casting. We're going to see everyone that wants to do it. We're going to need... three guys and a young woman."
-Joey's Two Cents: Murray was always the highlight of the franchise, so if he ends up not being a part of it, this film will really need to hit it out of the park with the new recruits casting...thoughts?
