Exact science is not an exact science
Oppenheimer had a veritable Murderers’ Row of good actors looking to work with Christopher Nolan and doing excellent work, telling a true story of the price of being a genius and living with the consequences of that knowledge.
Against that The Prestige had a similar array of actors doing excellent work, this time giving us a fictitious tale of an all-consuming rivalry between two magicians. But it also had David Bowie playing Nikola Tesla in a memorable supporting role.
I realise I probably shouldn’t let that tip the balance, but to my mind it does.
