The reboot of the 1984 classic is being directed by Paul Feig (Bridesmaids, The Heat). Aside from Wiig, Melissa McCarthy will also star in the film, as well as Saturday Night Live's Kate McKinnon and Leslie Jones. Thor star Chris Hemsworth will play a receptionist.
Feig whipped fans into a frenzy on Wednesday, when he tweeted out this photo of him handling slime.
"And ... action! #slimetimestartstomorrow," he teased.
