1. Leslie Thompkins
A social worker, physician and friend of Thomas Wayne, Leslie Thompkins was vital in the beginnings of Bruce Wayne. A new origin flick would be repetitive seeing as how
Batman Begins did a perfect job of displaying it. But, Bruces origin could be hinted at where as you know Leslie Thompkins was a part of it, but dont really have to show it through flashbacks or multiple scenes within the film. We know why Batman does what he does. Thompkins is an important character and should be displayed somehow. She helped to raise Bruce and that should be rewarded in the film by giving her an appearance.
