McClellan introduces Cal to the thugs at the warehouse using the same alias Terry gave him at the poker game, saying he's his financial advisor, however he then repeatedly calls him Dr. Lightman throughout the scene.
When McClellan goes "all in" against Lightman, he pushes in a big pile of chips against Lightman's much smaller pile. This is not how it works in "Texas No-Hold" poker. When "all in" is called, the bet becomes the size of whoever is holding the LEAST amount. This is something that Hollywood writers just can't seem to understand as this same mistake is made repeatedly in other shows and movies, such as 'Casino Royale (2006)'.
Agent Reynolds says Terry was in Belmarsh Prison from 1987 to 1990 but Belmarsh didn't open until 1991.
Terry hugs Cal at the beginning with a closed fist which means he is not used to such things,yet they share a close bond with each other from childhood.
