Frank and Hanna--weapons check
I just noticed that Frank and Vincent Hanna check the chamber of their pistols in the exact same way--by using using an index finger to pull the slide back about 1/3" to see that they have a round chambered. Frank does it in the car before he goes into L&A Plating while Hanna does it in the elevator on the way up to Hugh Benny's room. The man knows his weapons and is one of the few directors to favor authenticity over audacity when it come to the guns he includes in his films.
