I think everyone who likes the Truman show will like this link whether you are religious or not. I am not religious but open minded. When I first saw the Truman show, I was struck by it's deeper under tones and the philosophical questions it raises. I stumbled on this link to a site dedicated to these ideas, and it's absolutely fascinating. Please let me know if N E 1 else finds this interesting?

p.s. I'm also a fan of the Matrix which also has a constructed reality theme.
