References to Other Films
I saw a few:
"Until that day" is the parting line of European hit-man Joubert in "Three Days of the Condor."
"Fuck you in the eye-hole" seems a reference to GSGT Hartman's line "I'm gonna skull-fuck you..." in "Full Metal Jacket."
I don't remember the exact line, but one of Sarno's (James Caan's) threats reminded me of "Frank" his character in "Thief."
The names Parker and Longbaugh [sic] were the real names of Butch Cassidy (Robert Leroy Parker) and the Sundance Kid (Harry Alonzo LongAbaugh).
