Now i have never done this movie before lol. Here is a story i think should be the screen play: Lex Luthor teams up with Ra's Al Ghul to frame Batman for murder in Metropolis. Forcing Superman and Supergirl to Confront the Bat and his Family. Ra's Al Ghul:Jason Isaacs Watch Harry Potter and the Chamber of Secrets and you will know why i picked him. Talia: Jennifer Lopez She just looks the part and i think would do a great Talia. Lex Luthor:Billy Zane Who else can play him really? He was born for this part. Mercy:Joanie Laurer The Comic Book Version of Mercy is like a BodyBuilder. Batman:Russell Crowe He does a dark character that screams Batman. Batgirlina Meyer This is really a no brainer Nightwing: Go Unknown Actor Superman:Austin Peck Austin is an unknown actor and he looks the part much more than Brandon Fraser (Who would pick Brandon ,come on people). He also has the build for Superman. Supergirl:Sarah Michelle Geller Another No Brainer. She can play Linda and she can play Supergirl.
