All you need to know is that David Gale is in on the murder all along. There you go, just felt like spoiling the twist for you. Job well done I’d say! 
Seriously though, it’s a really good film.
havent seen it yet but a friend of mine said its cool but sad..:-)
Better than I expected (but then again, I do read the film reviews in Smash Hits magazine)
Looks like a good un. Might check it out - although maybe not now that I know that he was in on it all along. Tsk.
It sounded to predictable, I wasn't gonna watch it anyway :)
Thanks Sadi! 
yeah sadi --- thanks....i was thinking of seeing that one this weekend!
