Just over a week ago I went to see a film that affected me so deeply I think I’ve only just begun to process it now. It left me sweaty-palmed and short of breath. As the final credits rolled to a halt I was so restless I couldn’t bring myself to take the Tube home so I marched/ran home from Leicester Square, my heart racing with every step. Never before have I had such a physical reaction to a film. As I write this JK Simmons has just picked up a BAFTA for his role as Best Supporting Actor and deservedly so.
