According to Producer Joel Silver the film is likely to be in 3D:
“Logan’s Run depicts a dystopian future society in which population and the consumption of resources is managed and maintained in equilibrium by demanding the death of everyone upon reaching a particular age. The story follows the actions of Logan, a Sandman charged with enforcing the rule, as he tracks down and kills citizens who try to run from society’s lethal demand — only to end up running himself.”
May God save us from such a bleak future! An arbitrary shelf life for humans, how crazy!
