Casey Jones, fan favorite from the comics, cartoons, and late 80’s/early 90’s films will not have the same origin story he had in the comics. Amell attributes that to this movie introducing him at a different point in his life and development. He says Jones is a normal, law abiding man with a job, who loves hockey, and after being laughed off by law enforcement, he decides to take things into his own hands.
Hopefully the change won’t make audiences too angry, although it seems people are just looking for reasons to hate these movies. Michael Bay is the worst, but if you love TMNT it’s still best to give them a chance right?
