Query: Wayne is game as a cop on the case in London

Good movie overall. There something to be said about these gritty '70's cop films, with the grainy look, dated scores, and often hard to follow dialogue and story lines. John Wayne jumped into this "dirty harry" genre with this and McQ, with marginal success. Wayne is nearing 70 by this time, and in many ways looks it. He brings charm and style to any role he graces, but looks surpirsingly tired and worn out here. Perhaps his declining health had something to do with it, promting questions as to why he kept on working when so many others of his era had retired. He should have retired with True Grit, although his brave performance in The Shootist was a fitting swan song to the career of the finest actor America ever produced. There will never be another John Wayne.
