'Pineapple Express' is the name of the latest film from Hollywood's hottest young comedy star Seth Rogen.

And although the title may have you wondering what could this film possibly be about, if you are a fan of Mr Rogen's work to date - 'Knocked Up' and 'Superbad' being the most notable - then you shouldn't worry as, chances are, you're going to enjoy this film anyway.

This is actually Seth Rogen's second project as screenwriter collaborating with Evan Goldberg after last year's 'Superbad'. And while in that film Rogen only had a minor acting role, here he assumes the lead role of Dale Denton, a computer processor who enjoys a bit of weed now and again.

When not at work Dale spends his time hanging around with his drug dealer, and buddy, Saul (played by James Franco) exploring new ways of getting 'stoned'.

Dale is a bit of a dreamer - which may have something to do with the large quantity of drugs he inhales - and although not the most ambitious there seems to be no harm in him.

But the trouble for Dale starts when Saul introduces him to a new strain of weed known as 'Pineapple Express' - hence the title for the film.

When Dale witnesses a murder he panics and, fleeing the scene, he drops the drugs he has just purchased.

Things go from bad to worse when Saul informs him this drug is extremely rare, and will probably be able to be traced back to him - and then Dale - information which forces the pair to go 'on the run' from crooked, drug-dealing cops.

In much the same way that 'Superbad' worked as a buddy movie where young guys talk about the important things in life - girls, sex and slagging each other off - so the partnership between Rogen and Franco works to great comic effect here as Dale and Saul bitch to each other about the trouble there in, each blaming the other for their predicament.

In last year's 'Knocked Up' - which starred Rogen as Ben Stone (but for which he had no part in the writing) - Rogen played a layabout who was forced to grow up when he got a girl pregnant after a one-night stand.

Here his character is allowed a bit more room to develop - possibly thanks to the direction of David Gordon Green, who is well known as a director who can get the best out of his cast.

Rogen's co-star Franco will look familiar to anyone who has seen the 'Spiderman' movies (where he played Harry Osborn) but here his character he gets a chance to let his hair down and really have some fun.

Once the initial premise of the story has been established it pretty much turns into a chase caper where the leading duo wise-crack their way from one potentially dangerous situation to the next.

The film contains plenty of strong language, rude and crude comments as well as more action, and violence than you might expect from what is, basically, a buddy comedy with a dark edge to it.

Anyone looking for a strong anti-drugs message, or any message come to think of it, may be slightly disappointed because all the 'Pineapple Express' is - as its title may hint at - is a silly movie that is supposed to make the audience laugh.

Although it may initially seem Seth Rogen's brand of humour is not suited to all tastes, seeming to be directed squarely at a young male audience, the appeal of his movies to date suggest otherwise. And it would be surprising if 'Pineapple Express' is not a hit on a similar scale to those two films.
