I loved this movie, it was funny and entertaining and had me chuckling the whole way through. What makes this movie special is that for once, the alien is the cool guy, who actually seems to have a stronger grip on normal human activity than Graeme (Pegg) and Clive (Frost). This science-fiction/comedy is different because for once, the alien knows and understands earth and humans because he grew up there. The story follows Paul as he tries to make contact with his people and return home. This comedy almost mocks your usual sci-fi movie as Paul is the anti-alien. It is also quite a cute movie as there is an element of romance and of finding long-lost (and new!) friends. There are several moments where you think that one thing is going to happen, but these moments are cut short by Paul's strange habits and this keeps the comedy going. The story revolves around Graeme and Clive who visit America to go to some sci-fi conventions and visit the usual alien sites, such as Area 51. They soon meet Paul on their travels and soon becomes one big road trip to try and take Paul home, whilst on the run from government officials desperate to track Paul down after he escaped from their hold. There are some quite unexpected moments as people turn out to be somebody completely different to how you thought they would be. Perhaps what makes this movie really funny is the fact that Paul is a lot more human than he is alien. I highly recommend this movie to people of all ages and I guarantee you'll be laughing your way through this film.
