Continuity mistake: When Missy goes to talk to Cockroach, in most shots his sling has a tiny bit of blood on the white strap, but in one brief shot before she leaves the strap is twisted and the blood isn't visible. It goes back to visible in the next shot.
Continuity mistake: After Rackham enters the room and tells Cage to step away, Cage starts to walk to the door and Rackham is standing there with his arms crossed. In the next shot, his hands are down by his side.
Trivia: Just after Diamondback knocks out Misty, Luke walks out and we see a dumpster that reads "Timely Trash." A reference to Timely comics, the predecessor to Marvel.
