Because Gary Oldman is so good there are two films – one with him in it and one without him. After a good start, the screenplay weakens out and even goes off the rails. Oldman is perfect but he is not in it enough to save it.
Another political bio from a period in the USA that has been thrashed to death. It is well produced however and the makeup people do a great job cloning the actors (particularly the noses). Jennifer Jason Leigh's appearance is spot on.
