Personally I am not at all interested in the topic or the film, and the few scenes I`ve seen from it encoureged me to stay away from it. The only thing that could prompt me to watch it is the fact that it`s directed by Stephen Frears, though that doesn`t mean much nowadays. 

I like Hellen Mirren very much, but there arent any actors on earth who can make me watch a film just because of them, and especially not when they are giving "oscar-worthy" performances.
