The direction of The Sleeping Tiger was credited to Victor Hanbury, but this was actually a pseudonym for the blacklisted Joseph Losey, whose first British film this was. Alexander Knox stars as psychiatrist Clive Esmond, who believes that he can stem the criminal tendencies of young fugitive from justice Frank Clements (Dirk Bogarde). To this end, Esmond hides Clements in his own home. At first hostile towards the handsome crook, Esmond's wife Glenda (Alexis Smith) gradually warms up to her house guest, and before long she and Clements are casting lustful glances at one another. She intends to run off with Clements and make a new life for herself, when suddenly he decides that he actually wants to reform. If nothing else, The Sleeping Tiger is a fascinating precursor to the sexual tensions prevalent in Losey's later Harold Pinter adaptations. ~ Hal Erickson, Rovi
