“We can’t show you the show, we just finished filing this morning,” said Marvel TV boss Jeph Loeb today at the Marvel’s Iron Fist panel at New York Comic-Con. Then the Marvel TV boss showed the packed Main Stage at the Javits Center the new trailer for the March 17, 2017 debuting Netflix series.

Today’s panel for the 13-episode first season of the series saw Loeb, Iron Fist himself Finn Jones and showrunner Scott Buck onstage. Fellow cast members Jessica Henwick, David Wenham, Jessica Stroup and Tom Pelphrey.

Rosario Dawson was also on-stage on Saturday in NYC. A veteran of Daredevil, Jessica Jones and Luke Cake as Claire Temple, the actress was a surprise guest and new addition to the Iron First cast – to the delight of the crowd. It looks like the Temple character will be getting involved in some fisticuffs herself as Loeb and Dawson teased on stage.

The fourth Marvel series for Netflix, Iron Fist has Game of Thrones alum Jones as once missing billionaire by day and martial arts master and possessor of a mystical force by night Danny Rand. Like many a Marvel hero, Rand is trying to find himself amidst the conflicting responsibilities and burdens of his abilities. Rand “is riddled by contradictions,” Jones told Deadline earlier today.

With the countdown clock and chanting fans that Marvel has had at many a panel, the Iron Fist event started with a montage of Daredevil, Jessica Jones and Luke Cage footage to get the already energized crowd pumped up. Then the teaser for Iron Fist appeared the big screens. Several clips were shown throughout the panel including a hallway fight scene, a Marvel fave, that sees Jones’ character leave no man standing and Henwick’s Colleen Wing send two giant thugs to the ground in a schoolyard bare fisted street match.

This wasn’t the first time fans got a glimpse of Iron Fist, of course. A short first look at the series and the plane crash that found 10-year old Danny Rand lost to the world among the mountains was revealed at the Luke Cage panel during San Diego Comic-Con this summer.

With Punisher and Defenders reveals as well, Saturday’s jam-packed panelcomes literally just hours after Iron Fist finished shooting its Season 1 finale in NYC – with Loeb giving shout out to “the hardest working” crew, many of whom were in the hall. There will be little rest for Jones now filming on Iron Fist is over. While no premiere date has been set for The Defenders, the Daredevil, Jessica Jones, Luke Cage and Iron Fist team-up series starts filming in November – also in the Big Apple.

Also on the Main Stage today before the Iron Fist panel began was Erik LaRay Harvey, who plays Luke Cage villain Diamondback on the most recent Marvel series to launch. Kept under wraps until the Cheo Hodari Coker EP’d series debuted on September 30, the actor got big round of applause from the fans.

New York Comic-Con runs until October 9
