On paper, this movie looks like it would be good, however it never gels. The secret of Butterfly is no secret to anyone except Irons' character. There are huge holes in the story and I never felt connected or got a good understanding of any character. Though Irons, a top rate actor in my opinion, does as good a job as possible, it isn't enough to make this at all involving. For Cronenberg, who also directed Irons in the magnificent, Dead Ringers, this is a low point in his career. Irons, on the other hand, went on to do Die Hard 3.
