Seriously, what the heck is going on with Adam Sandler? In the eyes of many, Kevin Costner took the throne as worst actor-and-producer with his terrible 1997 trashfest The Postman. You could also make an equally compelling case for John Travolta’s 2000 project Battlefield Earth. But Sandler’s new film Jack & Jill significantly ups the ante. Surely it’s hard to top some of his previous outings in the producer’s chair, such as Joe Dirt, Deuce Bigelow: European Gigolo, or I Pronounce You Chuck & Larry, you may think – and correctly so.
