Like nearly everything else in Hollywood these days, the practice of releasing movie posters has been ramped up to the point of overexposure. On, let's say, a Monday, an attention-grabbing poster for a film like Spring Breakers surfaces online and gives off that iconic feeling of old; on that following Thursday, though, two new alternate one-sheets premiere on various blogs and instantly dilute the initial poster's impact.

Way back when, there was a simpler approach: Create one truly unforgettable image that captured the film's spirit while also generating excitement at just a glance. They were like pieces of art.

Will anyone remember the countless individual character sheets for this weekend's The Great Gatsby? Don't count on it. For better or worse, the wall space reserved for the 75 most iconic movie posters of all time shall remain undisturbed.
