The police file shows Bonomo's (Sylvester Stallone) date of birth as April 24, 1962, however, in the beginning when they are showing his mug shots, he has allegedly arrested in Clark County, Nevada on 01/29/1968 and Dade County, Florida on December 20, 1971. In both mug shots, he was clearly an adult, even though by those dates, he would have only been 5 on the date of the first arrest and 9 in the second one.
Near the end, Bonomo meets Kwon in a bar and he is drinking his 2 Bullets bourbon again. When they finish talking, Bonomo is shown tilting his glass all the way back to empty the glass. But when he puts the glass on the bar, we clearly see a small amount of bourbon left in the glass.
When Bonomo meets Kwon in the bar for the first time, Bonomo fills up his glass with his favorite 2 Bullet bourbon. He then drinks about half of the glass. While talking to Kwon he brings the glass back up to his mouth for another drink and the glass is full again.
Towards the end of the film, when Bonomo is in the warehouse, he climbs a set of stairs with graffiti on the side, in the next scene when he's reached the next level the same set of stairs is in the background of the shot.
When entering the toilet at the party, Christian Slater's (Marcus Baptiste) mask is down covering his face. The next shot, it is on his forehead. After being attacked by Stallone (Bobo), his mask is down and covering his face again.
When Bonomo and Kwon first meet in the bar, Bonomo pours himself a drink from the bottle he brought. You can clearly see bubbles resting on the top of the liquid in the bottle, indicating that it is not alcohol. Bubbles formed by agitation in alcohol dissolve extremely quickly, and it shows that it is either colored water, or more likely, tea, which is what is most often used to simulate whiskey in films or on TV.
Cop Taylor Kwon is shot twice into his right shoulder. In the last scene his partner James Bonomo meets Kwon in a bar. After Kwon suggests James cease his criminal activities, James gets up to leave. He taps on Kwon's left shoulder commenting 'did that hurt?', even though no harm was done to this shoulder.
