Directed by John Stockwell, starring Jessica Alba, Paul Walker, Scott Caan, Ashley Scott, Josh Brolin, James Frain and Tyson Beckford.

Director John Stockwell may well need to think twice before choosing to work on another movie like this. Un-inventive and cringe-worthy, 'Into the Blue' sets the wrong tone from the outset, and continues to ride on an out-of-control current from there onwards.

Trying to cram as much action as possible into a movie, regardless of its necessity or appropriateness, isn't always the best way to impact upon an audience. Take 'Into the Blue': very little storyline, very little depth and very little imagination – resulting in precious little incentive to go and see it. These days it seems you can't turn a corner without seeing a poster of Jessica Alba somewhere, and while her profile has definitely been raised in recent months, this film isn't likely to do anything for an actress on the up.

Alba stars as quiet do-gooder Sam, who is blissfully happy with the life she leads with boyfriend Jared (Walker) - that is until his old friend Bryce (Caan) turns up with his new girlfriend Amanda (Scott), bringing with them all kinds of chaos and mixing with the wrong kinds of people. Sam and Jared are into diving - exploring the sea, its inhabitants and the ship wrecks that occupy the depths. It's all very exciting...

But one day, when accompanied by Bryce and Amanda, they make a chance discovery, unearthing the remains of a famous, long-lost shipwreck, but along with it they find a stash of cocaine that has sunk to the floor of the sea after a plane crash. And suddenly this major moral dilemma is causing them all to examine their consciences and those of the people who share their secret.

It sounds like there's enough action here to string a half-decent film together, but the elements never seem to gel and we're left with lots of small subplots that don't have a huge impact, either individually or for the greater good of the overall story. You can spot the bad eggs a mile off in this movie and there are few surprises in terms of the character's motivations.

Alba, Walker and company probably don't deserve to be singled out for particular criticism. They have little decent material to work in the script and it all becomes tiring too quickly, through no obvious fault of the cast. The array of colourful underwater shots and aquatic novelties do little to detract from the fact that this is a very superficial film. It boasts action, adventure, sharks and drug-dealers but in reality there's barely a moment of suspense in it.

If you fancy spending two hours looking at Jessica Alba is a bikini, only alternated with shots of Jessica Alba in a wetsuit, then by all means part with your hard-earned cash for this. Otherwise, let it fade into the blue.
