Warner Bros. Animation and DC Entertainment have released a new still from their upcoming animated film, "Batman: The Killing Joke," featuring Batgirl.

In the adaptation, Barbara's time as the costumed Batgirl will be seen in a prologue sequence. Though Barbara was an important part of the original graphic novel's story, her superhero career was never explored. Actor Tara Strong, who voiced Barbara/Batgirl in numerous television series, animated features and video games dating back to 1997's "The New Batman Adventures," will reprise her role as the character.

Fueled by the return of Kevin Conroy as Batman and Mark Hamill as The Joker, witness the birth of a super villain, the fortitude of a hero and the punch line that will leave you speechless.
