Did they make a NightWing Cartoon, or coming out with a movie?

They should start making the animated series of Nightwing, and get a movie in the works. She still have Robin in the Titan TV series.

I thought a movie is in the works? Maybe it got cancelled which would be a shame cause he one of dc best

It hasn’t been officially cancelled. The director is actually working on another project at the moment, and even if he wasn’t World of DC is in a state of flux at present, so everything is up in the air right now.
