Though it meanders a little through the tale, Cronenberg's film still presents a fascinating look at the relationship of two larger-than-life individuals. The performances, even from the passing Vincent Cassel who is merely a blip in the story, are excellent but Keira Knightley's is worthy of particular mention. The actress is often criticized for her lack of emotion, a comment I have never agreed with, but here she is clearly a standout among some exceptional talents. Her slight Russian accent isn't overbearing and feels natural but it's her physical performance, her facial and physical contortions, some more subtle than others, that help make her character particularly memorable.
Though I didn't find it up to par with Cronenberg's usual brilliance, A Dangerous Method is an excellent film and a worthy addition to the Cronenberg library.
