Which cancelled/unproduced movies would you most like to see?

Which movies that were either cancelled, shelved, stuck in development hell or simply ended up unproduced would you have most liked to have seen?My personal choice would probably be Gladiator 2 because it's so absurd that I think it'd be enjoyable. Time-Travelling Gladiator Russel Crowe? Sign me up.(Superman Lives is another one, because Nicolas Cage as Superman would be a sight to see) via /r/movies http://ift.tt/2uLlBCP
