"Harry Potter" film series was the most successful franchise in movie history even before the final installment hit screens.It was a greatful film of the world than other film side and with "Deathly Hallows - Part 2" already breaking box-office records, it's becoming less and less likely that anything will ever match it's historic achievement. But that's not to say others haven't tried.
In the decade since "Potter" first hit screens, a host of other fantasy movies have tried to copy its formula for success. They were based on very popular books, they featured a plucky young hero, and they relied heavily on expensive visual effects. And while some made for passable movies, most never launched the sort of multi-film franchise that made "Potter" such a smash.
