There are loads of films out there that are scientifically inaccurate or seemingly impossible, one that springs to mind is The Fly, where someone tries to teleport but a fly gets in the machine too, so they end up as a human/fly hybrid. Most of science fiction is scientifically impossible (just now anyway). Was there anything you were thinking of in particular?
Hope this helps
The obvious one for this is Iron Man – I was watching number 2 when it came out in the cinema and there comes a point where it’s just rediculous (like when he creates a new element for his heart thing, and I think only takes him an afternoon!) It’s good entertainment though.
I wonder if the public really understands just how unrealistic it all is though?
