If Kendrick is serious about playing Robin, she could play an older version of Stephanie Brown, a character who takes up the Robin mantle briefly, before becoming Batgirl, and currently goes as Spoiler in DC Rebirth.
Unfortunately for Kendrick, Affleck is not sure if Robin will appear in his movie – either that or he just doesn’t like the idea of Kendrick playing the part.
When it comes to superhero sidekicks, there are not many that are as well-known as Batman’s faithful boy wonder Robin.
Even if her desire to play Robin is only for the point of the bit, it is an interesting proposal regardless.
