Good comments and I just want to add a great hard-boiled Peckinpah flick..."Bring Me The Head Of Alfredo Garcia"...I mean, where else can you see Warren Oates drunk-as-a-skunk and talking to a decapitated head?
Supposedly, more blank rounds were discharged during the production than live rounds were fired during the Mexican Revolution of 1914 around which the film is loosely based.
The shotout/massacre in the end took 12 days to film. When completed, about 10,000 squibs (simulated bullet hits) had been used.
