Assuming this information is legitimate, arguably the biggest shocker is that Cassandra Cain will be suited up as Batgirl rather than Barbara Gordon in Birds of Prey. Introduced in 1999, Cassandra is the daughter of assassin Lady Shiva and David Cain and was raised to be one of the greatest martial artists in the world. Sadly, her upbringing resulted in her never learning to speak and developing poor social skills. Despite Cassandra's dark past, Batman took her under his wing, and she served as Batgirl in the comics for many years, although she's also gone by Black Bat and Orphan. So despite Barbara usually being one of the founding members of the Birds of Prey, Cassandra will fill that role for the movie. This subsequently brings up two questions. One, will Barbara Gordon have any role to play in Birds of Prey? Two, does this mean that the Batgirl movie in development, which originally had Joss Whedon attached and is now being written by Christina Hodson, will star Cassandra instead of Barbara? Part of me wonders if Batgirl might be a prequel starring Barbara, but in the "present day" during Birds of Prey, she's now Oracle.
