Released amid the 1994 holiday season, it outpaced competitors by 150% in its opening weekend.
Jeff Daniels portrays Harry Dunne, Lloyd's equally clueless roommate and pet groomer, whose worm obsession and van-driving mishaps fuel 70% of the road-trip gags. Daniels, a stage actor transitioning to comedy, beat out 200 auditionees on March 10, 1994, per production notes, and his chemistry with Carrey generated 2.5 million DVD sales by 2000.
