'Dumb and Dumber To' starts filming [PHOTOS]

Jim Carrey and Jeff Daniels are really stoked to be back on set, filming the sequel to the inexplicable 1994 "Dumb and Dumber."

The stars met up in Atlanta Monday and immediately started sharing photos of themselves in their Harry and Lloyd getups.

Carrey also gave a cameo to his new children's book, "How Roland Rolls," about a wave afraid his life will be over the day he hits the beach. The book, written by Carrey and illustrated by Rob Nason based on Carrey's concept art, is aimed at children ages 4 to 8 and was released Monday.
