Bob Crane was the star of the hugely successful 1960s TV series "Hogan's Heroes", a man of fine upstanding character until he's befriended by a svengali-like video technician. Together the two men embark on an increasingly dark journey of sexual hedonism that leaves Crane increasingly estranged from reality and, ultimately, dead. Auto Focus is a fascinating film, visually atmospheric, superbly performed by the two leads and an utterly gripping account of one man's decent into addiction.
