Isla Fisher's new movie Keeping Up with the Joneses had one of the worst opening weekends ever.

The Aussie actress and Zach Galifianakis play a suburban couple who get caught up in an international espionage plot when they discover their neighbours (Jon Hamm and Gal Gadot) are government spies.

It opened in cinemas last week but died a quick death at the box office.

Keeping Up with the Joneses cost $52.5 million to make but pulled in just $7.3 million in the US on the weekend.

For those playing at home, that's the 10th worst opening weekend result for a movie released in more than 3000 theatres in the US (since 1982).

The dreadful box office performance isn't too surprising given the reviews for Keeping Up with the Joneses have been less than complimentary ... much less.

Here's what some critics had to say:

"Woody Allen said of true comedy: If it bends, it's funny. This movie snaps like a twig." - Tampa Bay Times

"The treatment for this action spoof could have been written on the back of a matchbox - of a single match, even." - Observer

"Galifianakis is one of the funniest people on the planet. To put him in a movie and have him recite unfunny lines is like driving a Porsche in the slow lane and never shifting out of first gear." - ABC News radio

"It is the sort of inoffensive comedy that fails to evoke any strong reaction - including laughter." - Washington Post

"It's the kind of movie that could be stomached if you were stuck at home on a rainy Sunday afternoon and you saw it on special for 99 cents on iTunes. But it's definitely not worth the price of entry at the cinema." -

"Only in a well-populated movie theatre can one truly appreciate the sound of silence when Gadot's character boasts she could crack a walnut with her vagina. And that, my friends, is the funniest joke in the picture." - Groucho Reviews

"It's a movie that is hampered by a script that feels all set-up and little pay-off." - NZ Herald
