Probably my favourite Tony Scott film, amidst stiff competition. The acting of both Hackman and Washington, plus the fine supporting cast, is top-drawer, and Scott keeps the suspense up, the film's as tight as a drum. It's rumoured that there were plenty of script doctors, including Quentin Tarantino, but that's no crime--especially when it works. One of my favourite submarine films--it's up there in my books with 'Destination Tokyo' (I haven't seen my DVD of 'Das Boot' yet). It's a great shame that Scott decided to take his life a few years back. He was a much better director than I used to give him credit for. I guess it's true that we don't realize just how good people are until they're gone. This film's essential for war film enthusiasts or those who enjoy suspense films or thrillers: It wouldn't be out of place in the oeuvres of, say, Sir Alfred Hitchcock or David Fincher, and would make a great double-bill with 'Lifeboat' or 'They Were Expendable'.
