I saw this one ages ago. It features a Godfather-era Pacino in a comedic role, and a pre-Lex Luthor Gene Hackman doing his best to be sensitively tough. Driven by dialogue, which is sometimes sketchy. There is a washed-out early 70s realism to the cinematography. Not bad, but it does drag at times. A counterpoint to Cool Hand Luke, perhaps.
Roger Ebert: three stars. Vincent Canby.
