I enjoyed this film quite a bit, it is a rare comedy that started kind of slowly, but continued to get more funny as it went on. Usually I find a lot of comedies start kind of fast then fade out kind of fast. This one has two Brits who are in the United States for comic con, the end all comic book, science fiction, horror and a whole heck of a lot more conventions. These particular two are into aliens and there to not only take in the sights and meet a favorite author, but to drive to some of the famous alien spots out in the west. Well they quickly run into some trouble with some local rednecks and then end up witnessing a very bad wreck. They go out to explore the scene and end up meeting Paul, an alien who is apparently on the run and in the need of assistance. During the course of their adventure the two Brits must keep Paul hidden from government agents and also deal with crazy religious fathers and all sorts of other things one tends to find on the road. Probably why I liked this one as I always enjoy a good traveling comedy of which this can certainly be classified as one. I also enjoy watching Simon Pegg and Nick Frost working together as they have a good chemistry. They are a couple of the few actors who I will watch a movie specifically because they are in it. I used to have a whole slew of actors and actresses like that, but these days not so much. The comedy is funny, like I said it started a bit slowly as I think the comic con scenes could have been a bit funnier, but it really got going once they met up with Paul. Not much of a Seth Rogen fan, but he did a fine job as the voice of Paul. So all in all a funny comedy that kept me entertained throughout.
