Graphic designer Tom Whalen created a nifty alternate poster for The Warriors, one of my favorite flicks from the '70s (it's hard to believe its badass synthesizer score, which every hip-hop DJ or cratedigger will tell you has got breaks galore, was written by the same composer who was involved with the not-so-Warriors-like "Nadia's Theme"):
The Warriors' controversial, poorly received original poster was a menacing-looking portrait of all the gangs from the film. Moviegoers wouldn't be this frightened by a one-sheet again until 2007, when a shirtless, Jim Morrison-spoofing John C. Reilly scared away 90 percent of Walk Hard: The Dewey Cox Story's target audience.
Here's another Whalen-designed alternate poster I like:
the official Shining poster designed by the legendary Saul Bass in 1980. Somewhere, a Bass fan who's following me on Twitter will read this and proceed to unfollow me.
