According to THR, Emory University booted the production after only two weeks, reportedly because they didn't appreciate the overtly raunchy nature of the production. (Quick question: Had anyone at the college either read the screenplay ... or seen the original Revenge of the Nerds? Was the college expecting a Disney flick?) So the Atomic folks tried to do some shooting at another school (Agnes Scott College), but the facilities simply weren't expansive enough to pass as a big-time party school.
With the holidays approaching, the production on hold, and all involved parties earning a paycheck, Atomic simply decided to stop the bleeding: Case and crew members have been sent home to enjoy Thanksgiving, and it looks like they'll all have a little unexpected free time for the next several weeks before moving on to projects that don't require the approval of any snippy college administrators.
