Red Hood will appear in the Stinger
I understand that in the comic Jason's return was teased by Clayface messing with Bruce, so it would make sense for Jason to appear at the end of the film, possibly hinting towards a new adaption of Under the Hood in the future.- Unfortunately, Jossed. There is no Stinger, with or without Jason Todd.
Harold Allnut will not be in the movie
Harold is really obscure, and he hasn't been shown to exist in this universe so far, so killing him off a la the comic would have no impact here.- Confirmed.
