Fan Casting The Brave and the Bold

My personal fancast for the upcoming DCU's Batman movie. I reallyw wish to see the whole Bat-Family in this film, and i think it would be an excellent touch to have plenty of the Batman villains in it no matter who the main threat is, but having them in montages of how Batman cotidianilly deals with them arresting them-having them escaping from Arkham-arrest again and so (maybe even a visit of Batman and Robin to Arkham to search for someone, but seeing the gallery of villains on the way, it can be an idea for this and next Batman movies in this universe)
