The Wild Bunch, which I can quote chapter and verse. Seen it about a hundred times since the first time in South San Francisco in '69, including seeing it in Munich in '71, dubbed in German. I guess you could say it has a law enforcement theme, though the law enforcers are an incredibly scummy pack of bounty hunters. Just great in every department: writing, acting, directing, photography, period authenticity and with the most revolutionary editing work seen until that time.
