Viewer Reviews Firepower is a surprisingly good late 70's thriller with James Coburn and Sophia Loren. All of the key elements are here--"faceless" billionaire a la Howard Hughes, the saavy renegade in James Coburn, and Sophia Loren looking as striking and stylish as always--while making you wonder what side she's on. The plot--bringing the billionaire to justice--is a so so one...but the aforementioned elements as well as several exotic Caribbean locales make this a worthwhile thriller with a good ending.
