Joss Whedon is primarily known for helming two Avengers movies for Marvel, but he actually became famous for creating and developing strong female characters. His stint with Marvel wasn't his first experience with the comic book movie genre; you might already know that he wrote the script for a Wonder Woman flick a few years ago.

Whedon laid low for a while after Avengers: Age of Ultron, but he recently surprised everyone when he announced his plan to write and direct a DCEU Batgirl movie (which will most likely be released along with other Batman-related movies in 2019). It’s safe to say that the project couldn't have found a better creator.

During an interview with The Hollywood Reporter, Whedon explained how he came up with the idea for a Batgirl flick. He wasn’t motivated by any desire to test his strength in another comic book movie shared universe, nor was he interested in making another action blockbuster with comic book characters. Instead, Batgirl’s motives for becoming a superhero attracted him to her in particular.

According to Whedon, Barbara Gordon's motivations may not be as clear as those of other heroes, including Batman:

She came up, and I started getting obsessed with how a young woman could get hardcore enough to need to put on the cowl. Like, what's her damage? She didn't have her parents killed in an alley. Who is this person, who decides  – rather than being forced to by their childhood trauma – decides to pick up this life? How intense and driven that person is"¦I just couldn't stop thinking about it.

This is certainly an interesting approach, and it might give us a hint as to what the Batgirl movie could be about. It could be an origin story as the DCEU should have done for its Justice League heroes.

Of course, the big question is whether or not the film will feature Batman and the Joker. Whedon didn't address this, saying:

I have a lot of voices in my head.
