Well, who else was he going to call? Director Paul Feig took to Twitter on Wednesday to reveal his all-female leads for his upcoming "Ghostbusters" reboot. It's no surprise that at the top of the marquee are Kristen Wiig and Melissa McCarthy, the stars of Feig’s megahit comedy “Bridesmaids.” McCarthy in particular has developed a De Niro-Scorsese like bond with the director, having also starred in Feig’s “The Heat” and the upcoming “Spy.” Rounding out the new-look “Ghostbusters” cast are “Saturday Night Live” vets Leslie Jones and Kate McKinnon. The fab foursome will be filling the proton packs once wielded by Bill Murray,Dan Aykroyd, Ernie Hudson and the late Harold Ramis, stars of the first two “Ghostbusters movies” in the ‘80s. Sony had high hopes for a third installment of the supernatural comedy franchise, but original director Ivan Reitman dropped out in the wake of his friend Ramis’ death last year. With the script for “Ghostbusters III” having to be severely rewritten in the wake of Ramis’ passing anyway and Bill Murray vowing not to return, an opening was created for Feig’s vision. "My favorite thing to do is work with funny women," Feig told Entertainment Weekly in October. "I was like, what if it was an all-female cast? If they were all women? Suddenly, my mind kind of exploded: that would be really fun."
