THE GIRL WHO KNEW TOO MUCH (1969 FILM)

'''The Girl Who Knew Too Much''' is a 1969 film starring Adam West as Johnny Cain, a nightclub owner and former freelance adventurer who is forced out of retirement when a crime syndicate boss is murdered in his nightclub and investigations lead into unexpected areas.
Tagline: "You have to be crazy or in love — to take on the syndicate!"
The film co-stars Nancy Kwan, Nehemiah Persoff, Robert Alda, Patricia Smith, David Brian, and noted jazz musician Buddy Greco as nightclub entertainer "Lucky".
The film was a vehicle for Adam West to escape his Batman stereotype by playing a cynical, hard-edged tough guy. Sample dialogue:
:Mrs. Smith: "And what do ''you'' do for a living, Mr. Cain?"
:Cain: "I kill people, Mrs. Smith."
The film was not much of a box office success in theatrical release, but became a staple of late-night showings on WCBS-TV and other television stations in the early 1970s. Despite this exposure, it has never been released on VHS or DVD, and thus is in danger of eventually becoming a lost film.
