This film adaptation of Irish playwright Brendan Behan's drama against capital punishment charms subtly. In fact, everything about it is low-key. Inattentive viewers might even miss key elements. Patrick McGoogan ably plays Crimmins, a new prison guard eager to see the inmates pay their just debt. Walter Machen is the veteran guard Regan, whose view of capital punishment and prison in general is considerably more nuanced. At question is the fate of "the quare fellow," a never-seen, never-heard inmate found guilty of murdering his brother. Will his execution go off as scheduled or will Regan and Crimmins in concert with Kathleen, the quare fellow's wife (Sylvia Syms), manage to have it called off? The movie is one of those filmed play types, and is dated into the bargain, but the questions it raises have neither been answered nor gone out of style.
