Design breakthrough: Sometimes a breakthrough is a beta test that turns out to be woefully wrong. The Fifth Element demonstrated beyond a shadow of a doubt that nobody wants the future to look like it was designed by aging French fashionistas who still think it's racy to reference the Virgin Mary.
Copycats: Thankfully there was no Sixth Element, but Fifth Element did launch the career of the world's first-ever female action star - Milla Jovovich. Sure there have been other women who played action roles, but Jovovich is the only one to play solely action heroes (see her wildly popular Resident Evil series). Hopefully her action hero career will not follow the trajectory of Arnold Schwarzenegger's, because that would mean she'd have to star in a series of terrible comedies before becoming a homophobic politician.
