When someone from the DC-loving crowd apparently yelled an expletive-laden anti-Marvel insult, Ayer repeated it.
Ayer said, as one can see from the cellphone video, naturally enough. He soon tweeted his regrets, saying he got "caught up" in the moment.
"Not cool," the director tweeted. "Respect for my brother filmmakers."
The premiere was attended by the "Suicide Squad" principal cast, including Will Smith, Jared Leto, Margot Robbie, Jai Courtney and Cara Delevigne.
