I really liked it too. Made me rotfl at times, and really sad at the end when Cancer-boy watches the film. And the last sentece was FTW!
It's a film about SW fans. And SW. And a bit about St, too. I mean, it does have Shatner in it. I don't know if it was shown in a cinema close to you, Dafty, but you should watch it if you can. Maybe it's out on DVD already? I think it is. You should not watch this film with people who have no clue about SW though. They will most likely not like it.
Amazon only does the American version, it seems... http://www.amazon.co.uk/Fanboys-DVD-Region-US-NTSC/dp/B0016MJ6GA/ref=sr_1_1?ie=UTF8&s=dvd&qid=1245165302&sr=8-1
