EXCLUSIVE: Sony Pictures has re-teamed Bad Teacher writers Gene Stupnitsky and Lee Eisenberg with director Jake Kasdan for a new untitled comedy. The logline: After a Supercuts manager advises his best friend to break off his engagement, he unexpectedly falls in love with the jilted fiancee, testing both his new romance and his friendship. Eisenberg and Stupnitsky will produce with Mosaic, which produced Bad Teacher. So far, they haven’t made progress on mounting a sequel to Bad Teacher, a film that cost around $20 million and grossed around $215 million worldwide. The writers also worked for Sony Pictures on Ghostbusters III. While there has been no shortage of rumors that actors are being cast and that production will begin on the third installment as soon as spring, I’m told that the studio isn’t going to make it without Bill Murray. And as recently as last month, he had not read the script, or if he did, he has not reached out to get the dealmaking started. Without him, I don’t think the film has a ghost of a chance.
