Spitfire asks its audience to stretch credibility way past the breaking point. Can any audience be expected to buy Katharine Hepburn as a faith healer, let alone as one who is so far backwoods that even the hillbillies might have a hard time claiming her? Hepburn was an enormously talented motion-picture actress, and while she should be commended for wanting to stretch herself, it has to be admitted that she was fundamentally unsuited for the role of Trigger. As miscast as she undoubtedly is, however, she's still interesting to watch, as she mouths religious bromides, lets loose her hair-trigger temper, and adopts an accent never heard before or since anywhere on this or any other planet. Hepburn tended to give her all to a part, and the sheer energy with which she attacks Trigger makes for entertainment. And, despite all the obstacles, Hepburn still manages to find moments when her talent bursts forth and she creates an indelible instant of screen magic. She gets little help from the script, but director John Cromwell at least finds ways of showing her off in the best light possible under the circumstances.
