High and low is a 1963 film directed by Akira Kurosawa, starring Toshiro Mifune, Tatsuya Nakadai and Kyōko Kagawa. It was loosely based on King's Ransom, an 87th Precinct police procedural by Ed McBain.(wikipedia)
"High and Low" focuses on Kingo Gondo (Toshiro Mifune), a powerhouse executive in the Japanese shoe industry. In the midst of an attempt to take over his company, a proposition that throws him in hock down to his own furniture, he's hit by a huge ransom demand, with a twist -- the kidnaper (Tsutomu Yamazaki) takes, not his own son, but his chauffeur's.
