Not a good movie, 'technically', but one of my all-time favorite comedies.

Rating: Null/10 (3 July 2001)

I avoided "Dumb and Dumber" at its theatrical release because I 'knew' a film of this name could not possibly be good. Boy was I wrong. I've seen it now 3 or 4 times, most recently last night, and for me it never gets old. In the vein of good farces like "Happy Gilmore" or "Something About Mary", this one manages to strike a good balance, carefully walking the line between belly laughs and actual gross-out.
Like the scene where Lloyd (Jim Carrey) puts laxative in the coffee of Harry (Jeff Daniels)and, arriving at Mary's (Lauren Holly) house we start to hear abdominal gurgles. Frantic, Harry finds the bathroom, pulls down his pants, sits -- when we hear Mary say, "Don't use the toilet, it doesn't flush." Then we see Harry, pants down to his ankles, taking apart the back of the toilet to try and make it work.
Or the scene where they are skiing and Harry, like a kid, touches his tongue to the frosty metal support. And later, as his tongue stretches, as mary pulls his head away. Or the last scene, where Lloyd and Harry direct the bus of bikini girls to the next town, instead of volunteering for the job of "rubbing oil all over their bodies."
And, of course, the whole idea of trading their hound mobile for a small scooter because it 'makes 70 miles per gallon', then riding to Aspen, in the snow, over passes, and arriving with ice growing from their noses, as Lloyd gets off in Aspen, Harry is stuck to his back. Trying to throw Mary's briefcase into a lake, it opens, they see all the money, then spend it all on a $285,000 car, a hotel suite, fancy clothes, all the while leaving "IOUs" in the suitcase so they could pay her back eventually.
Lauren Holly is a fine actress, but also one of the most strikingly beautiful. Here she was about 30 during filming, and at the absolute height of her beauty. No wonder Carrey married her, unfortunately it didn't last. Jeff Daniels is, to me, an even better comic than Jim Carrey, who is mostly "over the top" in his acting. Daniels is a more subtle, and funnier, comic.
No message in this film, just good fun and laughs. The actual story doesn't matter. My wife cannot stand "Dumb and Dumber". I guess it helps to be a bit wacky too.
Sept 2017 update: Still fresh after all these years.
