The deleted scenes that have not been released (up to another 30 minutes worth) are mainly the origin scenes, which were originally going to be used as flashbacks throughout the film but in the end were mainly used for the title sequence.

Perhaps they will be released in the future, but who knows. Because the ideal cut of the movie would be to use all deleted scenes and take the best parts and put them back into the film. Especially begin the movie with the new origin story and so on.

I think most of the scenes are quite worthwhile and I'd like to see a version of the film with all of them put back in but it would probably drag a bit and wouldn't be the ideal cut of the film.

My plan with this cut is not to use all deleted scenes, only the ones that helps to make the story better. I will probably use 30 min of the deleted scenes to make this extended cut.
