In an IGN Interview at SDCC Stephen Amell gave us some insight into the Casey Jones character he will be playing in the upcoming Teenage Mutant Ninja Turtles 2 Movie.
According to Amell, “It’s certainly not your father’s or your younger self’s Casey Jones, but that’s because we meet him at a very different time in his development, When things go awry, when he goes through the normal methods of what someone would do when they’re law-abiding citizen and he’s met with laughter and scorn, he decides to take things into his own hands.”
Unlike the comics, Casey Jones is an adult with a job as a construction worker (according to rumors) when he decides to take the law into his own hands. In the comics, he started crime fighting after his father’s auto shop was burned down and his mother and sister taken hostage by a local gang.
They might have changed his origins, but looking at the picture they haven’t changed much else. Casey still dons the hockey mask and battles with sports equipment.
