Photos: 'Ghostbusters': Where are they now? As the charming Dr. Peter Venkman, Bill Murray could do no wrong in the eyes of the audience. Not much has changed since then. Most recently Murray acted in "Monuments Men" and "The Grand Budapest Hotel," and this fall stars in the buzzworthy "St. Vincent." In 2015, he'll provide voice work in a movie that would make Venkman proud: the animated comedy "B.O.O.: Bureau of Otherworldly Operations." Hide Caption 3 of 11

Photos: 'Ghostbusters': Where are they now? "Ghostbusters" was the brainchild of "Saturday Night Live" veteran Dan Aykroyd, who has a thing for ghosts. The writer/actor/producer, who played Dr. Raymond Stantz, most recently starred in the 2014 James Brown biopic, "Get on Up." Hide Caption 4 of 11

Photos: 'Ghostbusters': Where are they now? Harold Ramis was at the heart of the success of "Ghostbusters" -- as both the co-writer and the lovable nerd Dr. Egon Spengler. Ramis died in February 2014 , but the legacy of his work lives on: from "Caddyshack" to "Stripes" to Egon's perennial safety tip ("Don't cross the streams!"). Hide Caption 5 of 11

Photos: 'Ghostbusters': Where are they now? No one could pull off being possessed while in full '80s glam like Sigourney Weaver. Her Dana Barrett was equal parts alluring and hilariously scary. These days, Weaver is devoting her talents to another huge franchise: She's at work on the sequel to 2009's "Avatar," due out in December 2016. Hide Caption 7 of 11

Photos: 'Ghostbusters': Where are they now? Louis Tully was also a demonic force to be reckoned with, but you couldn't help but feel badly for the guy with Rick Moranis playing him. After creating more family-friendly fare with the "Honey, I Shrunk the Kids" franchise and "The Flintstones," Moranis decided to retire from on-screen acting in 1997 to be a stay-at-home dad after his wife's death.

Photos: 'Ghostbusters': Where are they now? Annie Potts' Janine Melnitz may not have fought the ghosts like her employers did, but the secretary was just as tough as the boys.

Photos: 'Ghostbusters': Where are they now? William Atherton has a knack for playing annoying characters -- remember Richard Thornburg in "Die Hard"? -- and he put his talents to good use in "Ghostbusters" as a skeptical government official who kept getting in the way of the team's work. He appeared in the second season of Syfy's "Defiance." Hide Caption 10 of 11
