Are you sure? Writing about what a character is thinking is a big no-no for scriptwriting.An arguement can also be made that Blondie has never heard Tuco fire his pistol (except once when he was firing at Blondie's canteen but it isn't the same pattern). So how would he know Tuco's pattern?
So Clinton, you have a copy of the original script, or what? Is it on-line? Is it original or just something written later?
Am I the only one here who feels that Tuco probably just took a trip to a gun shop like he did when we first saw him construct his gun?
This was not a gaff or continuity error as Clint's actual dialog was dubbed over after filming. Clint actually said "Five to one makes it easy. That's a perfect number large one" which was dubbed to "Every gun makes it's own tune, and it's perfect timing large one"
