Since his trailer for "Public Enemies" hit the web recently I figured I would link to this TV movie that Michael Mann made in 1989. Basically it is a ruff draft for what became "Heat". As far as I know it never played on US tv but did get released in Japan. Here are the early versions of the DeNiro Pacino scene and the bank heist.
The actor in the DeNiro role, Alex McArthur had some bad luck in the 1980's. This movie never got released and he starred in William Freidkin's "Rampage" that was delayed for many years. He did play Madonna's boyfriend in her "Papa Don't Preach" video which was directed by James Foley, who also directed "Glengerry Glen Ross".
