Sony's reboot of the 1984 film puts the proton packs and particle throwers in the hands of Melissa McCarthy, Kristen Wiig, Leslie Jones and Kate McKinnon. Chris Hemsworth, Michael Kenneth Williams and Cecily Strong also star in the Paul Feig comedy. If it's a hit, it could pave the way for similar female-fronted remakes (despite some initial backlash to such castings).
