Jena Malone’s character was similarly cut out of Batman V. Superman: Dawn of Justice, but was added back in for the Ultimate Edition Blu-ray.
Kiersey Clemons hasn’t been able to reveal much about her time on the Justice League set, but she has voiced her excitement at being a part of the movie.
Even if Clemons is cut out of the movie, there is always the chance that she could appear in deleted scenes.
Given the unique story behind Justice League’s filming, I would not be surprised if some sort of extended edition ended up on store shelves.
