And the Oscar for Funniest Title goes to... Having sent up and celebrated horror movies in 'Shaun of the Dead' and tough guys in 'Hot Fuzz', Simon Pegg and Nick Frost experience some close encounters of the nerd kind in 'Paul'.

Graeme Willy (Pegg) and Clive Gollings (Frost) are two sci-fi obsessives on the trip of a lifetime. They've already lightened their wallets considerably at the legendary Comic-Con in San Diego and now they're hitting the highway in a camper van to visit the UFO hotspots of the American West.

And that's where their adventure will really begin.

On a deserted highway in the middle of the night, Graeme and Clive see a car go out of control and flip spectacularly into the sagebrush. Jumping out with phones at the ready to help, it turns out that the duo could be the ones needing the oxygen when they meet the survivor of the crash.

Paul (voiced by Rogen) is an alien on the run from the US Government. After humouring and educating all manner of spies, scientists and film directors - including Spielberg! - for 60 years, Paul has no more knowledge to share and believes that the scalpel is the only thing he has to look forward to. He asks Graeme and Clive to help him get to his rendezvous with the mothership and they agree. If the religious fanatics, rednecks and special agents further up the road don't get them, then maybe Paul's bad driving will.

Valuing the important people in your life, meeting some new ones, taking chances, fan boys becoming heroes, creationism vs Darwinism, Ewok love - Pegg and Frost cram a lot into the first movie they've written together but 'Paul' is as sweet as it is funny and while there are in-jokes aplenty, you don't have to have all the original 'Star Wars' figures in their boxes to enjoy this road trip.

A big part of Pegg and Frost's appeal is that there never seems to be much distance between them up on the screen and the people watching them, and so it proves again here. They perfectly capture the energy and dynamics of true friendship - the bickering and tender moments - and, if anything, the chemistry and timing between the two off-screen pals is even stronger than before. Proving that three isn't a crowd, they're joined by Rogen as Paul, a brilliant CGI creation who proves to be just as rib-tickling and adulation-worthy as his two geek angels.

Paul is set to make many new human friends who will want to see him again, and however much you liked Pegg and Frost before entering the cinema, you'll think even more of them on the way out.

Roll on 'The Adventures of Tintin: The Secret of the Unicorn'.
