As I read more literature and watch more movies, one thing I realize about critically acclaimed films and books -- most of them base their stories from religion, history, etc.. Almost like an allegory... -- I was wondering if I could ever successfully write my work without incorporating history or any serious event from the real world However, I also wanted to know -- could anybody think of movies or books that were entirely made up? And still were considered successful? I mean, even the Wizard Of OZ was some sort of political allegory. Thanks.
