Oh Justin Bieber, what a tease. Up for Robin, a Superman/Batman script called Batman Vs Superman, and based on the The Dark Knight Falls chapter of The Dark Knight Returns, where Batman fights Superman, crediting Frank Miller and Klaus Janson…
In which Robin was a young woman called Carrie Kelley. Hmm.
Unless of course, as he tweeted hours before…
Off to do something funny or…die :)
