Hmmm! Anyone seeing a pattern here. Heath Ledger, check. Joseph Gordon-Levitt, check. No, you don't see it? Okay, so maybe it is only obvious to me.
Think back about ten years or so. Remember a certain particular teen romance comedy? Yup, I am talking about 10 Things I Hate About You.
That would mean in the fourth movie upcoming in the new Batman series, and we all know it is coming (it is just a matter of time, unless of course they decide it is time to reboot the series yet again) we might see Julia Styles or David Krumholtz. In what roles, I have no idea. Perhaps The Huntress and Calender Man respectively, long time of favorites of Batman fans.
Then again, they could always get Freddie Prinze Jr. Awesome no?
