kate beckinsale as catwoman (i just think she is so hot and from seeing the underworld movies she can play a sexy badass)
hugh laurie as the riddler (i know everyone wants johnny deep but i could see him doin a good job)
hugo weaving+cgi as clayface (ok so clayface is one of the coolest batman villians and i know that nolan's batman is set in the real world but batman has superpowed villians plain and simple and i would like to see clayface on the big screen and hugo weaving would do a great job at voicing him)
michelle rodriguez as posin ivy (same reason as clayface and i think she can pull off crazy plant lady)
sarah silverman as harley quinn ( i mean come on she is hot and funny she is perfect for this role)
ok now for the one guy who i think could do a great job at taking over as the joker............
michael shannon as the joker ( ok so i was watching that movie revolutionary road with leonardo dicaprio and this guy has a part in the movie as a crazy guy and the entire time i was thinking that this guy would be a fantastic joker if u get a chance check it out he was crazy good! lol)
thats my cast let me know what you think!!!
