The Hypnotist (U.S. title Scotland Yard Dragnet) is a 1957 British thriller film directed and written by Montgomery Tully and starring Paul Carpenter, Patricia Roc and Roland Culver.

The Monthly Film Bulletin wrote: "The narrative of this murder mystery is so hung about with rambling and unconnected sub-plots as to become hopelessly confused.

A most inept performance by Paul Carpenter only adds to the muddle; but there is some good playing by Kay Callard and Ellen Pollock.

"[3] The Radio Times wrote "Irish-born director Montgomery Tully was one of the key figures in the British B-movie industry during the 1950s and 1960s.

This is one of his better efforts, as psychiatrist Roland Culver attempts to frame disturbed test pilot Paul Carpenter for the murder of his wife.
