The movie is about John Paul Getty, a billionaire who was reluctant to pay his grandson’s ransom after his kidnapping. Sounds like real sleazebag, so Spacey was a great choice for the role.
The movie is finished, Ridley Scott by his own choice is re-shooting all the scenes with Spacey at what is likely tremendous expense. Afraid no one would go to see it if Spacey was in it I guess, still seems silly to me, the film is finished.
Christopher Plummer? I say “Go all in.”. Go with this guy:
