'Dumb and Dumber 2' was definitely happening. And then it was off. But then Jim Carrey was back and it was back on again. And now, according to director Peter Farrelly, it's "100% guaranteed that it's a possibility." They're in talks with Warner Bros. for the sequel - titled 'Dumb and Dumber To' - and want Channing Tatum and Emma Stone to join Carrey and Jeff Daniels.
