Akira Kuroswa's "High and Low" offers about twenty times the value of "Inception" at roughly the same running time. (It plays today at 6:30 at the AFI Silver.) It's a "police procedural" so exciting and so emotionally committed that it transcends its genre. Kurosawa (shown above, left, with Francis Ford Coppola, middle, and George Lucas, right) got the hook for the movie from an Ed McBain novel, "King's Ransom." A principled shoe executive (Toshiro Mifune) is about to use his borrowings and savings to take over the business when he's told that his son has been kidnapped. In an odd turn the real victim turns out to be his chauffeur's son. Mifune pays the ransom anyway, knowing that competing executives will force him out of the company.
