So, pretty much what I was afraid of. Sigh.
Guess I'll stick with the Henry Fonda/Charlton Heston/Glenn Ford/Robert Mitchum/Hal Holbrook/Toshiro Mifune version from 1976 (also featuring Mr. Miyagi, Ponch from CHiPs, Magnum P.I., and Miami Dolphins running back Larry Csonka in supporting or bit roles).
