Corrected entry: Brad says he'll pay David $100K for the job but they say $500K when discussing how much they'll each receive outside the RV. (00:12:50 - 01:26:34)
Corrected entry: In the end of the movie, when they deliver the drugs, Brad says it's all here, but we know it's not, because of the "baby" that was run over by the semi trucks earlier.
Corrected entry: When at the airport, look closely at the IDs of David and Kenny, they have different addresses even though they live in the same apartment block.
Correction: There's a good chance David, being a drug dealer, has a fake ID, and/or moves around frequently to avoid the police.
Correction: Then you missed the scene where David calls Brad outside the hospital and asks for "hazard pay" and asks for $500K, which Brad agrees to.
