A fairly enjoyable thriller with no particular depth or complexity, stylishly shot in black-and-white by Philip Lathrop and stylishly directed by Blake Edwards.
The real pleasures of the film are its stars, the ever vexing Lee Remick and the ever reliable Glenn Ford, and a super-cool score by Henry Mancini.
It was recently released in an excellent Blu-ray edition by Twilight Time, with the memorable score available on an isolated track.
