The movie's basic joke holds that the overbearing, unselfconscious Americans will do anything and say anything (and usually as loudly as possible), while the timorous British are nearly too polite to breathe.
Los Angeles Times:
Low comedy at high speed, it pretends to be a caper movie about a smooth London jewel heist and its infinitely complex aftermath. Actually, it's a smart farce about ingrained cultural differences.
Somehow, the movie manages to do the impossible: It makes John Cleese less than hilarious.
Perhaps the most unusual aspect of what is surely the year's most original and daring comedy is that John Cleese is not the funniest performer in it. Believe it or not, that honor goes to none other than the usually somber Kevin Kline.
New York Times:
It's not easy to describe the movie's accumulating dimness or to understand what went wrong.
Like many of the best English comedies, much of the humor here is based on character, good-natured high spirits, and fairly uninhibited vulgarity.
When it comes to comedians, everyone has their favorite. Mine is John Cleese.
Wanda defies gravity, in both senses of the word, and redefines a great comic tradition.
There's nothing deep, nothing ground-breaking, but it's a never-dull, tightly scripted yarn with some very funny gags.
Though it is less tasteless, irreverent and satirical than the Python pics, film still is wacky and occasionally outrageous in its own, distinctly British way.
It'll keep you amused enough to sit still and even remember it fondly. But it seems a light day's fishing for Messers Cleese and Palin.
