At the time ,like so many others such as Dalton Trumbo,Joseph Losey used to work under pseudos because of his commie friends.

"The sleeping tiger" predates permanent features in the director's work:

-the intruder ,be it a servant "(eponymous movie) ,a licentious gypsy ("the gypsy and the gentleman" ),some kind of doppelganger ("Monsieur Klein" ,perhaps his masterpiece), a mysterious girl ("secret ceremony"),who makes the place his very own ,physically ("The servant" ) or mentally ('Monsieur Klein" ).Dirk Bogarde is fascinating in his part of a young offender :his acting is so subtle we do not know when the movie ends whether he is a victim or a perverse person,probably both.

-the depiction of the decay of a milieu the intruder will destroy : the old aristocracy in "the gypsy and the gentleman" ,the bourgeoisie in "the servant" the world of the war profiteers in " Monsieur Klein" . When Alexis Smith tells her husband's guinea pig that she got a raw deal too when she was a child but she made her way of life just the same ,the guy knows better :"because you think you are happy now?"

A shrink wants to study a case of delinquency and wakens the sleeping tiger...which is perhaps not the one you are thinking of.

Superlative performances by the three leads.
