The filmmaking world of the early noughties was a different one to now in many ways. Brett Ratner and McG were being considered for big properties. J.J. Abrams was, conversely, not a viable director. And everybody was still in thrall to the mega-successful Matrix, because the crummy sequels hadn't soured everyone. Which doesn't mean that Superman: Flyby was going to be in an way a deep, philosphical study of Clark Kent - perhaps about the nature of what it means to be an alien, the dynamics of power and the like - but that it would've ripped off all of the zero-gravity bullet-time fights. To wit: the bad guys that Superman was set to fight in the film (before they clambered in their surely unnecessary mech suits) came at him with something called Kryptonian Kung-Fu, which would've probably looked something like this. Only way more stupid. Better or worse than the last act of Man Of Steel?
