Now, new concept art has revealed that characters like Shredder, Krang, and human good guy Casey Jones could have looked much different than they did in the final film.
The postings also reveal that Casey Jones (portrayed in the film by Arrow’s Stephen Amell) could have looked much more like his comic-book counterpart.
But while the mask and at least one hockey stick both make brief appearances in Out of The Shadows, otherwise the new Jones mostly just looks like Amell.
Master Splinter and The Shredder also received makeovers between films, bringing both more into line with their prior animated and live-action interpretations.
