In 1989, "Ghostbusters II" was released in theaters where it did well in terms of profit, less so in terms of critical response. Reviews didn't matter, though — the original 1984 film was so popular that fans couldn't wait to see a third sequel.

They waited. And waited. Various scripts were written, but due to a number of setbacks, "Ghostbusters III" never materialized. In 2014, 25 years after the sequel was released, it was announced that a new "Ghostbusters" film was on the way, with Paul Feig as director and the four lead roles to be played by women.

A lot of people took issue with the idea of an all-female cast, even though the roles are played by a talented batch of comedians: Melissa McCarthy (as Dr. Abby Yates), Kristen Wiig (as Dr. Erin Gilbert), Leslie Jones (as Patty Tolan) and Kate McKinnon (as Dr. Jillian Holtzmann).
