One-joke comedies are so hard to pull off. It’s Pat, The Hot Chick, Chairman of the Board, Bio-Dome, Dude, Where’s My Car? and just about anything by the Wayans brothers and/or Jason Friedberg and Aaron Seltzer are just terrible. And yet there is a way to make a good one-joke comedy. It’s been done before. The joke in Ghostbusters (1984) is that they’re pest control for ghosts, but they somehow manage to make that joke work the whole way through the film. The joke in Arsenic and Old Lace is that two sweet old women are serial killers, and only their nephew knows it. Groundhog Day repeats the same day’s events over and over, but it keeps getting funnier and more dramatic as time goes by.
And then there are the two films I’m going to talk about: Liar Liar and Mr. Magoo. The respective jokes are that one character can’t lie and the other can’t see. Despite both revolving around a single joke, these two films could not be more divergent in terms of execution. Liar Liar is so good that it singlehandedly changed Roger Ebert’s mind about Jim Carrey, suddenly turning him into a fan of the comedian overnight. Mr. Magoo, on the other hand, was so bad that it earned a spot in Ebert’s book, I Hated, Hated, Hated This Movie, in which he described it as, “transcendently bad… There is not a laugh in it. Not one. I counted.”
Both of these films were released in 1997, and I think there are no better examples of the right way and the wrong way to do a one-joke comedy than these two. So let’s go through all the ways that one film got everything right and the other got everything wrong. Continue reading
