Sigourney Weaver hit the stage of New York Comic Con today to huge applause to be revealed as playing the villain on the upcoming The Defenders on Netflix. The Oscar nominee was joined by the actual Defenders themselves Luke Cage, Daredevil, Jessica Jones and Iron Fist at the end of the Main Stage panel for the latter March 17, 2017 debuting series.

No details of Weaver’s character nor a premiere date for The Defenders was announced but the NYC-based series is about to start filming in the next few weeks now that Iron First‘s first season wrapped this morning. Weaver’s appearance came at the end of the Iron Fist panel at NYCC that also saw some Punisher news dropped too with Daredevil alum Deborah Ann Woll joining vigilante Frank Castle in the spinoff.

Marvel is honored to have an actress of her caliber and status join what is already our biggest show ever!,”said Marvel TV boss Jeph Loeb on Saturday. “She is by definition a class act.”

The Weaver announcement also saw Mike Colter (Luke Cage), Krysten Ritter (Jessica Jones), Charlie Cox (Daredevil) and Finn Jones (Iron Fist) together for the first time in public.

The quartet met up digitally earlier this week when Ritter crashed a Facebook Live session that her Jessica Jones Season 1 co-star was doing to promote the September 30 debuting Luke Cage. Cox and Jones, who Colter had never met at all before, also dropped in on the online chat to the great delight of fans watching.

While Daredevil has been renewed for a third season and Jessica Jones for a Season 2, neither have been given premiere dates yet. Luke Cage looks certain to get another season, especially after seemingly crashing the streaming service for a bit the day after its 13-episode first run launched – but nothing official has been said yet. As for Iron Fist, its first season begins next spring on Netflix.

New York Comic-Con continues until tomorrow but Sunday panels are going to have a hard time beating the effort of Marvel and Netflix tonight.
