Dumb and Dumber
Dumb and Dumber is the platonic ideal of the American gross-out road comedy: two catastrophically dim best friends, a stolen briefcase of ransom money, and a cross-country drive fuelled by mutual devotion and staggering incompetence. Carrey and Daniels commit so completely to the idiocy that it becomes weirdly tender. For anyone who finds sincere stupidity the funniest thing on earth.

Tommy Boy1995no page yet
Chris Farley and David Spade run their own version of the loyal idiot and exasperated straight man, road-tripping to save a family business with the same big-hearted, physical-comedy chaos.
But Farley's manic energy is relentless and the plot is just as thin — it's pure vibes, not story.
There's Something About Mary1998no page yet
Same Farrelly Brothers DNA — sweetness buried under increasingly filthy gags — but built around a more elaborate farce engine and an even messier love triangle.
But The gross-out set pieces go further and hit meaner than anything Lloyd and Harry ever do.
Ace Ventura: Pet Detective1994no page yet
Jim Carrey unleashed the same year, in full elastic-faced, boundary-erasing mode, playing a different but equally gloriously stupid creation.
But It's a one-man showcase rather than a double act, so you lose the buddy chemistry that makes this one sing.
The wildcard
Something you would not have found on your own.
Duck Soup1933
Same anarchic trust in stupidity as a comic engine — nonsense logic, escalating absurdity, characters who never once acknowledge how ridiculous they're being — six decades before Lloyd and Harry.
The Marx Brothers invented this register of gleeful, structureless idiocy; watching it is like seeing Dumb and Dumber's ancestor operate at full anarchic speed.
But It's black-and-white and stagey, and the jokes come from wordplay and vaudeville timing rather than physical gross-out.

More like this (8)
Airplane!1980
The granddaddy of committed-idiot comedy — everyone plays absurdity completely straight, which is the exact trick Carrey and Daniels are running here.
But It's spoof-format, gag-a-minute rather than character comedy, so the rhythm is looser and more scattershot.

Zoolander2001
Ben Stiller's male model is another towering monument to confident stupidity, dropped into a genre parody with the same anything-goes silliness.
But The fashion-world satire has aged oddly and some jokes lean hard on very-2001 cultural references.

Anchorman: The Legend of Ron Burgundy2004
Will Ferrell's newsroom idiot is cut from the same cloth — supremely confident, catastrophically unaware — with the same improv-heavy, quotable energy.
But It's more ensemble sketch than tight buddy story, so the plot wanders even further than this one's does.

Step Brothers2008
Will Ferrell and John C. Reilly play two grown men with the emotional maturity of children — buddy idiocy dialed up to a nearly feral degree.
But It's louder and more aggressively juvenile, without much of the sweetness that softens Lloyd and Harry.

Wayne's World 21993no page yet
Two devoted, none-too-bright best friends chase a dream with the same infectious, puppyish enthusiasm that makes Lloyd and Harry so likable.
But It's gentler and more sketch-based, without the road-trip structure or the gross-out escalation.
Bill & Ted's Excellent Adventure1989
The prototype dumb-duo road trip — two amiable dimwits, an impossible mission, and a friendship so pure it carries the whole movie.
But It's aimed at a younger audience and its time-travel plot is far tamer than anything here.

Of Mice and Men1992no page yet
Strip the jokes away and you're left with the same core relationship: a devoted friend shepherding a good-hearted, limited one through a world that keeps punishing them for it.
It plays the exact same friendship dynamic as tragedy instead of comedy, and the shift makes you see Lloyd and Harry's bond in a completely different light.
But It's a genuinely sad, slow drama about disability and loneliness — nothing here is built to make you laugh.
The Trip2010
Same setup — two mismatched friends driving through scenery, one oblivious to how insufferable he's being — but performed as dry, semi-improvised banter instead of American slapstick.
Steve Coogan and Rob Brydon play exaggerated versions of themselves bickering across a restaurant tour, and the low-key one-upmanship is its own quiet kind of hilarious.
But There's no plot and no gross-out gags — the humor is dry, verbal and very British, a world away from this film's chaos.
