Steve Carell dropped by "The Tonight Show" to talk up the upcoming sequel to "Anchorman." While he didn't reveal too many plot details, Carell did give an update on how much his character, Brick, has changed since the 2004 original film.

"He will not evolve. He will devolve," Carell said. "That was my hope with the movie, that it’s just going to be exactly the same."

Considering the worldwide success the first film enjoyed, this is probably the right idea. One change that will happen, however, is the inclusion of even more funny faces in the cast, including Kristen Wiig as Brick's love interest.

In addition to making "Anchorman: The Legend Continues" a star-packed affair, director Adam McKay is working in musical numbers to make the film a truly memorable experience. The "Anchorman" sequel is currently sheduled to open on Dec. 20, 2013.
