"Dumb and Dumber" spawed an animated television show and a prequel film entitled "Dumb and Dumberer: When Harry Met Lloyd" which starred Eric Christian Olsen and Derek Richardson in the title roles. I actually enjoyed the prequel but it was critically panned and did not do well at the box office. A sequel featuring original cast members Jim Carrey and Jeff Daniels would likely fair far better. Of course, the Bob and Peter Farrelly are busy working on "The Three Stooges" remake at the moment, so a sequel to "Dumb and Dumber" would likely happen sometime after filming wraps on that project.
There is always a chance Jim Carrey and/or Jeff Daniels may pass on the project as well. If they should decide to do another "Dumb and Dumber" movie, I'll be one of the first ones at the theater to watch it.
On another note regarding Jeff Daniels and sequels, I would love to see Jeff Daniels, Tom Berenger or Bruce Boxleitner, and Martin Sheen or Robert Duvall return for "The Last Full Measure". Last I heard about that film, it was dead because "Gods and Generals" lost money. I would love to see Ted Turner produce the final book of the Shaara's civil war saga. Michael Shaara wrote the novel "The Killer Angels" on which the film "Gettysburg" was based and his son Jeffrey Shaara wrote a prequel entitled "Gods and Generals" (which was made into a film as well) and a sequel novel entitled "The Last Full Measure". I still hope Ted Turner changes his mind and makes this last film.
Take care everyone and come back here often!
