Here's Why Emma Stone Turned Down 'Ghostbusters 3'

It was 'a whole thing.'

When Paul Feig was first asked "Who you gonna call?" for his all-female "Ghostbusters 3" cast, he had our forever girlcrush Emma Stone at the top of his mind -- and so did everyone else, after Bill Murray totally vetted her for the gig and made us all WANT it to happen so hard.

But after her experience becoming an international BFD thanks to the "Amazing Spider-Man" series, she wanted none of that franchise business, it seems. Sadface.

"The script was really funny," she told Wall Street Journal Magazine of her decision to pass on the opportunity to raze snot-looking supernatural stuff. "It just didn't feel like the right time for me. A franchise is a big commitment -- it's a whole thing. I think I maybe need a minute before I dive back into that water."

A whole thing. Well, that explains everything.

In the meantime, she's just been off getting nominated for an Academy Award and arriving as Woody Allen's newest lady muse -- but that's a whole other thing, we guess.

We can't be too sad about this miss, though, because the funny lady foursome that ended up signing up to slip on proton packs for the long-overdue sequel -- that is, Melissa McCarthy, Kristen Wiig, Kate McKinnon and Leslie Jones -- are pretty awesome all their own.

And, besides, we'll always have that "Zombieland" movie moment where she perfectly impersonated Annie Potts as the receptionist. So, that's at least something.
