Live-Action Titans Series Casts Anna Diop As Starfire

Zoe Saldana is actually Latina.  Just like Gina Torres.  They both are cast as black a lot because of their darker skin tone.

But about Diop. I see a lot of people are mostly mentioning her age rather than her ethnicity.  They have a 13 year old Raven, but Starfire is about to be 30...  Would be cool if they were actually doing the Teen Titans instead of calling them Titans so they don't have to worry about age.  Since she is that old, I'm guessing Nightwing will be around the same age.  And does that mean the Nightwing movie is off?
