It would be impossible to perfectly capture the chemistry between Billy Murray, Dan Aykroyd and Harold Ramis and, thankfully, Paul Feig doesn’t intend to. For this reason, we’ve chose four potential ghostbusters rather than assign specific actresses to each former character’s persona. First up is Kristen Wiig. Not only is she a known favorite of Feig (she co-wrote the script of Bridesmaids and starred in it), she has an uncanny ability for unfettered improvisation and quirky punch lines.

Although Paul Feig is not adhering to the original plot, we imagine that there will be a character that summons the Ghostbusters for their help. In the original film, Sigourney Weaver’s character reluctantly consults the Ghostbusters after some strange occurrences take place in her Upper West Side apartment. She staves off Bill Murray’s incessant flirtation, but ultimately falls in love with him. We don’t think that it’s necessary that a love connection exist in the new film, tut if there were to be a “Sigourney Weaver,” it should be Jon Hamm. Although he’s known as a good-looking womanizer in Mad Men, he has proven time and time again that he’s actually funny; he had a reoccurring role in 30 Rock, successfully hosted SNL twice, and played Kristen Wiig’s one-night-stand in Bridesmaids. 

There has already been much speculation over the potential cast of this movie, and Melissa McCarthy is on the rumored short list. Not only was in The Heat, but she also stole the limelight in Bridesmaids as the hysterically crude Megan. Bill Murray, her co-star in the upcoming film St. Vincent, is quoted in saying that she would make a spectacular Ghostbuster and we concur.

If there’s a Sigourney Weaver character, then there must be a Rick Moranis. He played Louis Tully, the obnoxious accountant who lives down the hall from Weaver’s character and relentlessly pursues her to no avail. Ellie Kemper would perfectly fill this role. She’s talented at playing someone sweet and aloof, with an off-kilter humor. Like most of our other choices, she was also in Bridesmaids, playing the awkward newlywed. She’s known as depicting Erin Hannon on The Office and even plays a reoccurring character in The Mindy Project as a psychotic ex-girlfriend.

Emma Stone is adept at playing funny girls in romantic and stoner comedies alike, and has risen to fame with her raspy voice and charm. It would be fantastic to see her in an all-female comedy and represent the younger generation of funny actresses.

With her characteristically dry and often dark humor, Aubrey Plaza would make a great Ghostbuster Number Two. She’s known for playing April Ludgate, the apathetic intern with endless deadpan one-liners on Parks and Recreation. We could see her as the Ghostbuster who is demonically obsessed with ghosts and monsters and who secretly gains pleasure in watching them wreak havoc on the physical plane.
