Earlier today, it was confirmed that director Paul Feig has cast his Bridesmaids stars Kristen Wiig and Melissa McCarthy in the highly-anticipated Ghostbusters reboot, along with Saturday Night Live breakout stars Kate McKinnon and Leslie Jones. There have also been rumors of a primary male role that has yet to be cast, with Hitfix reporting that the filmmakers are eyeing Game of Thrones star Peter Dinklage to play the villain, described as a mechanical genius, and original Ghostbusters star Bill Murray to play another pivotal character named Martin Heiss.

Not much is said about the villain, but Bill Murray's Martin Heiss is said to be similar to William Atherton's Walter Peck from the original, a "professional ghost debunker." After he sees some of the videos these new Ghostbusters post online, he becomes determined to prove that they're fake, and "ends up at odds with the team through the whole film." This would fall in line with previous reports that the reboot doesn't have any ties to the original Ghostbusters franchise, but leaves it open for original cast members to come back as different characters.

The first two lead characters of the reboot are Erin Gabler and Abby Bergman, former colleagues who co-wrote a book together on the paranormal before going in opposite directions. While Erin now works for Columbia University, getting close to her tenure, Abby is now working in the ghost hunting business with a new partner named Jillian. The site speculates that Kristen Wiig is Erin, Leslie Jones is Abby, and Kate McKinnon is Jillian, with Melissa McCarthy set to play the fourth lead, Patty, an MTA subway employee who discovers the main ghost in the movie. None of these characters' identities have been confirmed at this time.

Screenwriter Katie Dippold is still working on the screenplay before production begins, with the site speculating that what they saw was still very early in the scripting process, so it's possible these details may change. Paul Feig confirmed earlier this month that he will shoot the reboot in New York City, but it isn't known when production may begin.
