I posted this in another forum, I am new here, but this is what I said about the Penguin and Rupert Thorne. Tell me what you think . . .
The Penguin could also fit very well into this new, more modern age. He could be an English arms dealer, named Oswald Cobblepot, who realizes that Gotham’s government is falling (due to the recent hacks by the Riddler) and begins providing for the arising mob. He supplies to various families, such as the Falcone and Thorne families. He does not have to be shown much, but make him a threat because of what he deals out to the mob. Give him a role about the length of Detective Flass in Batman Begins, although, make him a bit more sinister.
Actor I prefer/recommend-Alfred Molina (I doubt he would consider playing another villain after Doctor Octopus, but he is still my main choice)
Rupert Thorne could have a role about the same length of time Salvatore Maroni or Carmine Falcone had. A short, but substantial role. Show Thorne as taking total control over the mob. He is in deals with Cobblepot/The Penguin and the Riddler and make it as if he has a desire to control Gotham, and with Gotham’s major systems failing, including the main Government, he nearly succeeds. This way, Gotham reverts back to being ‘controlled by criminality’ making a desire for the Batman to return and redeem himself.
Actor I prefer/recommend-Brain Cox (I read somewhere else that someone recommended him and I agree)
