This is one of the 70s better and most under rated thrillers of that era! It has a fantastic sound track by the maestro, Georges Garvarentz, an intriguing cast (Telly Savalas, Peter Fonda, Hugh O'Brian, O. J. Simpson, Maud Adams and Christopher Lee- the latter two are both excellent in this film!). It's a very thrilling experience, and one I did not forget in a hurry! 10/ 10!!!! AA+++
