More questions than answers

Rating: 10/10 (5 October 2019)

I will start by saying this film contains one of the greatest performances I have ever seen on screen. If there is no Oscar I will be amazed. Now for the question that ties to the ending.....is any of it real? There are at the beginning of the film two clocks both show the same time...is one the delusion and one the real and thus is any of it real apart from the one clock and the ending? Just my mind seeing other levels as we already know he sees a fabrication so is the whole thing a fabrication from within his cell?
I will leave it with you.
