Not really, though it’s more possible than you might think. According to MTV, Super Max writer Justin Marks says that he “remains hopeful” that Black Canary might make it into the Green Arrow prison break movie.
It’s a long shot, since the movie’s all about Green Arrow being stuck behind bars with lots of DC bad guys like Lex Luthor, the Joker, and the Riddler, but Marks says that “she’s obviously a huge part of Ollie’s life and now that they’re married especially.”
How hard would it be to show her worrying about Ollie and maybe even help him escape from the outside? That took me like two seconds to figure out.
