At first rather annoying in its heavy emphasis on reenactments, this movie ultimately proves fascinating, simply because the complicated, highly dramatic tale it tells still almost defies belief.

This film is so real. It treats its characters with so much care and sensitivity.

One of the most extraordinary films you will see this year. Take that as you want.

It's simply great fun, a winsome film and an occasionally over-the-top luxury fantasy that never flags.
