My memory of this is vague - thank God - but I remember thinking that The Whole Nine Yards was desperately unamusing, and confusing to boot. One bit that I do remember was was two gangsters dying in a burning car and this being played for laughs. Waka waka!
However a quick scan on IMDB shows a surprising level of support.
Liar Liar was very unfunny (I saw it in a theater and no one in the audience laughed at any of it), but not painfully so. The jokes weren’t exactly misfires; they were just terminally mediocre.
If I may disagree that the least funny movie of all time must be intended as a comedy, I would like to nominate Leaving Las Vegas. Not a lot of laughs in that one.
Going along with the OP, Canadian Bacon is pretty awful. The only remotely funny scene is where they force them to write their anti-Canuck graffiti in French as well, but that gag is lifted from Monty Python so there you have it.
I don’t think it works, though, if a large portion of people find it funny yet others don’t. I acknowledge Monty Python is not funny to many people, but there’s tons who find it hilarious. I found the Big Liebowski kind of stupid and Anchormen worse, but lots of people find them both funny. I think it has to be a movie that many people - really, the majority - find unfunny.
I’ll second the nomination for the Jerk. Maybe Bruce Almighty? But there were a couple of funny scenes in there. I don’t really think this can be conclusively decided, actually.
Then you have a better memory then me… the only thing I can remember is wanting those 2 hours of my life back…even the dog bit me to tell me how bad a movie that was.
OK, I guess someone has to come in here to defend The Jerk. I am not even a huge Steve Martin fan, I enjoy maybe 50% of his films, but I thought that was one of the good ones. Steve Martin tends to be a bit too blatantly silly and slapstick for me, but this is one film in which it worked. I still love the line, “I was born a poor black child.”
Broken Lizard’s Club Dread is the most unfunny comedy I have personally witnessed. It stars Bill Paxton as a Jimmy Buffet-esque singer/owner of a resort under seige by a serial killer. If simultaneously fails as a Scary Movie spoof, Scream genre mocking film and as an Evil Dead witty horror comedy. Not even Brittany Daniels (Joe Dirt) running around in a bikini for half the film makes it watchable.
Very few laughs. And I liked the aforementioned Super Troopers. It wasn’t consistently funny by any stretch of the imagination end to end, but you need to find it funny when the cop orders a burger at the fast food place and the kid says into the microphone, “it’s for a cop.”
And the “yes sir / yeah sure” bit is damn near a classic.
Club Dread, OTOH, had NOTHING. I mean, Pina Colada Burg? Who wrote that thing, an 8th grader?
