I think Harland Williams would work nicely.

My cast would be…

Will Smith
Jennifer Love Hewitt
Jack Black
Jimmy Fallon

A W' & 3 J's is what you get with my cast and it “W”ork's “J”ack. I mean Will can be the leader who generally one of the more educated ghostbusters, he'd be my main character. Jennifer Love Hewiit can be kind of a disturbed character like what's her face on EGB, Kylie or something. Dye her hair some shades of blue and she'd look crazy, she said she loved Ghostbusters in an E! interview. Jack Black would be are accident prone GB who would be afraid of his own shadown but in the in get the job done while overcoming his fear. Jimmy Fallon would be the disinterested, wise guy who always has a comment for everything like Venkman and tries to hit on Jen Love like Edwardo does to Kylie if that the characters name in EGB. I guess then Will could be Roland, and Jack Black could be the wheel chair character. I stand firm behind Will, Jack & Jimmy I guess we could find anybody for Kylie or a female character like Brittany Murphy or somebody else.

That could work but it doesnt necessarily have to be the exact same as EGB but thats a pretty solid cast none the less.

I would so love to see Dan, Harold, Bill, and Ernie back, but if there could only be new Ghostbusters than Matthew Broderick would be great. I also possibly see David Duchovny, Ben Stiller, Owen Wilson, Chris Tucker, Mike Myers, and maybe even Judge Reinhold or Tim Allen as the new group of Ghostbusters. Or if you were to go for a younger generation of Ghostbusters you could use Frankie Muniz, Tom Welling, Colin Farrel, and Ashton Kutcher. Than if you were looking for a female Ghostbuster than Sarah Michelle Gellar would top my list.

If Frankie Muniz becomes a Ghostbuster, then I'm defecting to Gozer's side.

lol. I doubt they want anyone that young.

Why not have Malcome-Jamal-Warner Winston?

Now that's the most original idea I've heard all day. Warner as Winston. Hmm… Well, He'd have to loose his dred locks because then he'd be exactly the same character in Dan's original script that was mentioned in the Staxx report. Although, It'd be interesting to see Warner as Winston. But, I'd much rather stick to my guns with having either Samuel. L. Jackson as a Winston-like character or Bernie Mac.

Aykroyd
Ramis
Hudson


And for the new team a couple of unknowns…
Troy Benjamin
Ronald Edward Daniels( A damn good actor if I do say so myself, you got to see him in the Diary of Anne Frank.)
David Schwimmer


You people shouldn't ask me to compile lists.. :p

Well,This is my talent list for a GB3:
Dan Aykroyd
Harold Ramis
Ernie Hudson
Bill Murray
The original four as mentors to a new group of GBs ( I also like this idea.)

Cast for a new group of GBs should be either:
Chris Kattan
Matthew Lillard
Will Smith
Samuel L. Jackson
Jeff Goldblum
Tobey maguire
John Leguizamo
Natalie Portman
Milla Jovovich
Michelle Rodriguez
Any of these actors (I think would make a good Ghostbuster ) should be cast in a Ghostbusters 3, which Sony/Columbia/TriStar should make!!!! :@ :-@ (o_O)
