Gang, trying to keep surprises but this is about to leak, so I'll tell you myself: the awesome Sigourney Weaver is going to be in our movie!
— Paul Feig (@paulfeig) September 25, 2015So basically the entire main cast is back except for Rick Moranis (who seems happier in retirement) and Harold Ramis (passed away last year). And I guess William Atherton aka dickless EPA villain, but I don't really know who cares if he appeared.
No one is reprising their original roles. Their cameos are as brand new characters.
