Gotham City Sirens Movie: Everything You Need To Know
4. The Joker And Batman Aren’t Confirmed
As it stands, the only actor listed on Gotham City Sirens' IMDb page is Margot Robbie herself.
Jared Leto's Joker has not been confirmed yet, but seems likely to show up in some capacity, even if it's just to explain why Harley is branching out on her own rather than hanging out with him after Suicide Squad. Some fans wanted more Leto last time, and others would've been happy if he was removed altogether - it'll be interesting to see how the powers-that-be respond to that.
Ben Affleck's Batman isn't attached yet, either. It would be odd for a film with Gotham in the title not to feature the city's most famous resident, but Batfleck is busy writing, starring in and producing his own DC film at the moment. Would he even have time to shoot a cameo?
