Here in the UK, everyone knows that there ain't no party like an S-Club party. As you would expect, they like to a party a little differently on the other side of the pond; their efforts mostly involve a lot of weak beer and some peculiar bobbing and weaving they pass off as dancing.

It's probably this disappointing show at partying that got the makers of this film to create the ultimate fictional party on film. And to make sure it went off with a bang, they even got a Brit to direct it too.

House parties can be pretty lame for high school students (see above for reasons why), which is why Costa (Oliver Cooper) and JB (Jonathan Daniel Brown) want to throw a really memorable one for their friend Thomas' seventeenth birthday. They're helped by the fact that his parents are going out of town, so they can invite one or two of their friends round for a quiet social gathering.

His dad isn't that worried about anything untoward happening either, as he considers his son and his friends to be social losers. And he's not wrong. But what he neglects to consider is the coming together of out of control hormones with the power of social media.

With a guest list fixed at fifty people, Thomas is assured that nothing can go wrong. But a handful of people soon turns into hundreds. Then thousands. And the trio soon find themselves at the centre of the mother of all parties.

As expected, the newly introduced water volleyball event at the London Olympics draws an impressive crowd.

This film behaves like an unofficial prequel to The Hangover films. To find Hangover director Todd Philips as producer then is no great surprise. The three central characters are almost the Hangover gang in one massive flashback during their high school years.

It doesn't really attempt to be an all-out gross comedy; instead, it tries to balance comic elements with a sheen of MTV style cool. Overall, it gets the balance right. There's a lot of fun to be had, usually at the expense of a picked on Yorkshire terrier, a pissed off midget and two twelve-year-olds who head security.

Brit Nima Nourizadeh, making his directorial debut, manages to give this tired old story a welcome freshness, mainly by the approach of one of the teens documenting the whole party on camera, as well as a soundtrack that must surely be considered pleasing to the ears of most teens.

He also gets natural performances from his three leads, who act like they could well be friends in real life.

It's the kind of party that the Superbad kids could only dream of. Let's not get ahead of ourselves though, it's still not in the same league as a party thrown by the S-Clubbers, but still manages to be surprisingly entertaining nonetheless.
