Stevenson's career followed exactly the same trajectory as that of Alfred Hitchcock - he was discovered by Michael Balcon, feted at home and then lured off to Hollywood by David O Selznick. (He went on to direct Mary Poppins and The Love Bug.) In the '30s, he was considered one of the most promising British talents around. This risible horror pic (co-scripted by Sidney Gilliat) does little to explain why. It's a far-fetched yarn about a scientist with an unlikely ability to transplant brains from one body to another. Stiff performances and creaking dialogue.
