Although the lead role is taken by the wonderful Melissa McCarthy (love Mike and Molly), I don't know the supporting cast, Kristen Wiig, Leslie Jones and Kate McKinnon (I have heard of Wiig).
The WORST thing about the project is it is now being called a 'Reboot', a lazy Hollywood ploy to parasitically feed off a previous great film or franchise. So, we all know now it's NOT Ghostbusters 3, so call it something else. (RANT!)
