Jason Bateman as Peter Venkman
Bateman has the perfect smarmy, yet likable quality for Venkman. I think he'd be great.
Steve Zahn as Ray Stantz
Stantz is the heart and soul of the Ghost Busters and Zahn is one of my favorite actors who fit right into this role.
Jeremy Davies as Egon Spengler
Davies was great as the Goldblum-esque scientist Faraday on Lost. I'd love to see him as Egon.
Idris Elba as Winston Zeddemore
Zeddemore is the "every man" of the team. Elba is suitably cool I think.
Kristen Wiig as Janine Melnitz
I can't think of a better choice.
Elizabeth Banks as Dana Barrett
She would have great chemistry with Bateman and I just really like her.
Rhys Darbys as Louis Tully
Darbys is absolutely hilarious. An over the top role like Tully would be great for him.
William Fichtner as Walter Peck
Fichtner is always fun in "love to hate him" roles.
Doug Jones as Gozer
Just look at him! Perfect!
