Watch Dumb & Dumber Online – Free Streaming 1994 Full Movie HD on Putlocker. The sports car Harry and Lloyd purchase is a Lamborghini Diablo. Supplied courtesy of Emich Lamborghini, Golden, Colorado – which has since closed down. I would recommend it to anyone who enjoys Farrley Brothers’ movies, or anyone who likes Jim Carrey. It’s a hilarious comedy and the two stars were perfectly casted, especially Jim Carrey, of course.
