I have to believe this movie served some kind of inspiration for the much more successful Transporter films and T.V. series..the choice of George C. Scott seems a little weird..but maybe not anymore than when he played the lead in an Exorcist sequel..
shareI think the idea here is that he is playing a "Transporter" character who is retired, and comes back for the cinematic cliche "one last job."
So, his character is about being older, burned out, and doing this because he finds it's the only thing he knows how to do.
