Paul follows two British comic book geeks, Graeme Willy (Simon Pegg) and Clive Gollings (Nick Frost), who are visiting the US to attend Comic-Con, a large comic book and popular arts convention. Being huge sci-fi fans, they planned a road trip to go to see all the famous UFO sites across the America. While outside Area 51, they accidentally meet Paul (Seth Rogen), an alien on the run who was held captive there by the government for the last 60 years. When the government decides that Paul had outlived his usefulness, Paul launched an escape. Being a matter of life and death, Graeme and Clive take the rude, wise-cracking little alien aboard their rented RV. Now they are being chased by government agents and also the fanatic father of Ruth (Kisten Wiig), a young woman whom the two had to kidnap to prevent her from telling the authorities about Paul. Graeme and Clive are in for the road trip of their life as they take Paul to rendezvous with his mother ship.

On the one hand, this movie is funny and entertaining to watch. Pegg, Frost and Rogen are an amazing trio who gives the audience a lot of laughs and Wiig delivers all her lines in a spectacularly funny way. There are also many popular sci-fi references littered throughout the movie. Sci-fi and movie buffs will get a kick out of those.

On the other hand, this R-rated movie is full of swearing (I lost count of the number of times the word f*ck was used), lowbrow humour and attacks on Christianity. I cringed at all the sexual parts that were mentioned just for fun in this movie but the other people at the screening seemed love it. There is a scene where there is a small debate on God and evolution. Christians may not like it, it was very controversial and there are other jokes made at the expense of Christians. But if you can keep an open mind, as many will, the scenes are rather funny.

Overall I liked the story, it was hilarious, the animation is very realistic and I suppose that for being R-rated it is rather tame...Just don't bring your parents to see it.

Paul opens in theatres Friday, March 18, 2011.
