The Ones We Leave Behind - S1-E12
Revealing mistake: When Matt is running across the rooftops doing Parkour to keep up with the car he's following, there is a shot of him running towards another roof about to jump. In this shot, it's clear there is a stunt double in Charlie Cox's place. (00:29:27)
Frank Castle: You know the one thing you just can't see? You're only one bad day away from being me.
Trivia: During their dinner, Vanessa mentions a prince in a white suit and an ascot, to which Fisk replies, "it's a bit much." In the comics Fisk has been drawn almost exclusively in a white suit and ascot.
Question: Are there any obvious nods to the previous 2003 film version? A friend said he thought he caught a few subtle nods to it, but I don't recall seeing any during the first two seasons.
Answer: There are none. Only nods to the comics.
