For some reason, I have a whole plot and cast list set out in my mind for the Batman sequel.
Returning cast / characters:
Christian Bale as Bruce Wayne / Batman
Joseph Gordon - Levitt as Blake
Anne Hathaway as Selina Kyle / Catwoman
Morgan Freeman as Fox
Michael Caine as Alfred
New cast / characters:
Winona Ryder as Dr. Pamela Isley / Poison Ivy
Naomi Watts as Dr. Chase Meridian
Basic plot is that the film begins with Bruce and Selina being on vacation together in Europe when a thief guns down Selina in their hotel lobby while robbing the front desk. This brings back terrible memories of when his parents were killed and he is forced to confide in psychologist Chase Meridian. Meanwhile, Pamela Isley is a science teacher at a Gotham high school, but when an experiment turns wrong she is subjected to deadly poisons which then allow her to make contact with nature. She over runs the city with trees, vines and other stuff. In my mind, there is an epic scene in which thick tree vines wrap around a tall building and begin to crush it (much like a boa constrictor).
