I read in a newspaper a comment from one of the actors: “The biggest joke was on Catherine [Zeta Jones]: She actually thought we made a real movie”. Well, that sums it up: This movie does not want to be taken seriously, and you can see that all the actors had a lot of fun doing it.
I personally liked it. Nothing like Ocean’s 11, but definitely not worse. Different. More “fun”. But the end is a bit artificial nonetheless. Anyhow, worth to see in any case.
