One of the big names for Sci-Fi genre junkies, Dan O’Bannon passed away from Crohn’s Disease on Thursday. Besides the iconic Alien Franchise (or at least Ridley’s Scott’s first entry), O’Bannon also wrote at the high and low ends of the science fiction spectrum including Screamers, Blade Runner (he was one of many involved in the screenplay, somebody will surely corret me if I’m wrong on this, but many of the writers were uncredited as the screenplay went through a ridiculous number of drafts before productions started), Tobe Hooper’s Lifeforce, Invaders From Mars, John Carpenter’s Darkstar, Paul Verhoeven’s Total Recall and John Badham’s Blue Thunder. He also directed the cult zom-com favourite, Return of the Living Dead (pictured, sort of, above)
