2 great actors come together in a nail biting thriller from the first class. The two conflicting personalities do not back down one bit as they clash on issues of domination, race and dooms day events. Submarine thrilers are intnese as it is but these first class actors take it up one extra notch in their strugle. I watched this movie few times and it never gets old. I for sure suggest it to anyone and everyone who likes a classy film and a wonderful well written and acted drama.
