Clint Eastwood is at the top of his game in this thriller. He is bank robber Frank Morris, Incarcerated in one of America's most impregnable prisons, under the menacing gaze of warden Patrick McGoohan. He quickly concludes that he has little left to live for but escape. Together with twins Clarence and John Anglin (Fred Ward and Jack Thibeau) he puts together an intricate plan to escape their prison by using the utility tunnels to escape the complex then some makeshift inflatables to get across San Francisco bay. The facts of the story mean the ending is never in doubt - insofar as we actually know what the ending was/is! Now that rather detracts from any sense of jeopardy with the screenplay, but is one of the aspects that make Eastwood all the more compelling - his meticulous planning, ingenuity and sheer perspicacity is enthralling - ok, at times a little slow - to watch. He has to deal with the odd internal fracas, most notably from "Wolf" (Bruce Fisher) who would have some fun with him, if you get my drift... but none of that detracts him from his goal. Aside from this mission, Don Siegel offers us quite a detailed glimpse into life behind bars towards the end of this crumbling building's life; and we are exposed to the relentless tedium and despair of many which engenders some sympathy - however evil they may have been to be sent there in the first place. What Siegel doesn't really do, though, is use McGoohan to much effect. His usual less-is-more style of performance is certainly here, but all to infrequently to really build an sense of menace. Still, it's Eastwood's film and he is great...
