Director Troy Miller follows up the little-seen Mr. Show movie Run Ronnie Run! with this prequel to Dumb and Dumber, the 1994 box-office smash that starred Jim Carrey and Jeff Daniels and launched the careers of writer/directors Peter Farrelly and Bobby Farrelly. For the follow-up, were taken back to 1986 when Lloyd Christmas (Eric Christian Olsen) and Harry Dunne (Derek Richardson) first met while in high school. Dissatisfied with their being stuck in remedial classes, the dense duo sets out to prove that they can attend classes with their peers of normal intelligence. Along the way, they encounter a greedy principal played by Eugene Levy and a friendly janitor played by Luis Guzman who takes Lloyd under his wing. Along with Mimi Rogers as Harrys mom, Mrs. Dunne, Dumb and Dumberer also features performances by Rachel Nichols and Cheri Oteri. ~ Matthew Tobey, All Movie Guide
