When Tony (Frank Sinatra) talks to the clerk at the Vaca Cut 'boatel', the view from over the shoulder of the clerk, there is a photo/card in his shirt pocket that sticks up over the edge of the pocket. In the opposite view, nothing is in his pocket.
Hollywood always vastly overestimates the speed with which chloroform is effective. It takes at least five minutes of constant application to induce loss of consciousness and then must be applied continuously to maintain unconsciousness. Also, the chin must be supported to prevent the tongue from obstructing the airway. There is also a high risk of possibly-fatal cardiac arrhythmia with it's use, which was one of the major factors in its being discontinued as a surgical anesthetic.
