Sony has released four character posters showcasing each new member of the Ghostbusters team, a day after the first official ensemble picture was released (see “Geek Movie Image Round Up.”)

The four posters were spread across the EW, Time, People, and InStyle websites.

They introduce each actress’s character: Kristen Wiig’s Erin Gilbert, Melissa McCarthy’s Abby Yates, Kate McKinnon’s Jillian Holtzmann and Leslie Jones’s Patty Tolan.

According to the EW story, Wigg describes Gilbert as a “particle physicist, academic firebrand, spectral warrior.” Yates is a scientist, Holtzmann is an avant garde researcher, and Tolan is the transportation official.

All four posters can be seen in the gallery below.
