Can I just say to those above who recommended The Prestige - what a pile of absolute shit, I just don't get why anyone could possibly rate that film at all - boring, convoluted, badly acted and generally just a shite story line. I bought it (second hand thankfully) on Amazon after seeing some of the comments above, along with a second hand copy of The Illusionist, which I haven't, and won't bother to watch seeing as it is apparently rated as 'worse' than The Prestige!! Both are being dumped out for charity bag collection later this week.
Whilst I didn't rate illusionist, personally, it seems most of my friends who have seen both would like one and slate the other. Perhaps you'll enjoy illusionist, so should still give it a go.
