Which producer is credited on Supergirl alongside James Gunn?

Peter Safran is credited as a producer on Supergirl alongside James Gunn. The pair are the co-chiefs of DC Studios, and DC’s official movie page lists both executives as producers of the film.

Safran’s involvement is not incidental: he and Gunn were appointed to lead DC Studios and shape the new DC Universe’s connected film and television strategy. Safran is an experienced producer whose earlier credits include several horror and superhero projects, while Gunn is known both as a filmmaker and as the writer-director of Guardians of the Galaxy and Superman.

The other choices are associated with prominent DC productions but are not the credited producing partner in this question. Walter Hamada previously led DC Films, Deborah Snyder produced several earlier DC movies, and Charles Roven has produced major films including entries in the Batman and Superman franchises. Their involvement in the wider DC film history makes the options plausible, but Supergirl’s listed producer pairing is Gunn and Safran.
