MAN ON A SWING, purportedly based on a true case, is a puzzling crime thriller concerning a clairvoyant who helps find a murderer. After a murder is committed, supposed clairvoyant Franklin Wills goes to police Chief Lee Tucker (Cliff Robertson) and gives him details of the crime that he has seen in visions. The details are startlingly correct and could only have been known to the killer. Tucker, not convinced that Wills is indeed clairvoyant, begins to suspect him of the murder. MAN ON A SWING, directed by Frank Perry, over-complicates its central theme, distracting the viewer from the film's strong central theme, the ambiguity of Wills. Joel Grey gives an outstanding, scene-stealing performance in that role, giving Wills both menace and a surprising vulnerability. Cliff Robertson is far-less successful in his portrayal of the no-nonsense police chief. The film's ambiguous ending should increase the suspense of the film but instead further confuses the viewer. However, because of the superb performance of Grey, MAN ON A SWING is worth a view.
