The director of Marvel's "The Punisher" slipped up and revealed the action series will debut the first season in November. Director Dearbhla Walsh announced the date even as Netflix has yet to make this official.

In an interview with The Hollywood Reporter, Dearbhla Walsh discussed working on TV sets in both U.S. and U.K. productions. She said some of her work from months ago, have not yet aired, including one for "The Punisher" which she did last Christmas."But it's not airing until November," she said.

Walsh further said she worked on this episode from "The Punisher" across New Yok and Los Angeles for the editing.

But filming the episode were also done in Canada, where she later had to direct an episode of "Fargo."

What Netflix says

Walsh's statement comes as Netflix is still set to drop another Marvel series, "The Defenders," on Aug. 18. Fans note the streaming site might have been planning to announce "The Punisher's" release date when this show has been streamed this summer. Fans assumed the director pre-empted Netflix's plans. As of press time, the streaming site has not commented on Dearbhla Walsh's revelation.

"The Defenders" features four superheroes from Hell's Kitchen -- Daredevil/Matt Murdock (Charlie Cox), Luke Cage (Mike Colter), Jessica Jones (Krysten Ritter) and the Iron Fist/Danny Rand (Finn Jones).

All four characters have their own solo series on Netflix. Earlier, reports said Frank Castle a.k.a. The Punisher (Jon Bernthal) could likely make an appearance in "The Defenders" as he did in the second season of "Daredevil."

'The Punisher' cast, plot details

While Marvel and Netflix viewers were introduced to "The Punisher" on "Daredevil" in early 2016, the plot to his solo series remains unclear.

What's known so far is that the show has cast Ben Barnes as Frank Castle's oldest friend Billy Russo. The show also enlisted Ebon Moss-Bachrach as the tech geek Micro/David Leiberman. Karen Page (Deborah Ann Woll), who made a connection with Frank Castle on "Daredevil," is also expected to be in the series.

Fans believe the show's timeline will take place after the events that will unfold in "The Defenders." Like all of Marvel and Netflix's superhero series, "The Punisher" will have 13 episodes.

"You know, this whole superhero-comic-book thing is something I had zero interest in being a part of," Bernthal told GQ in December. But since doing the show, he has learned to embrace the comic book culture and its fans, whom he calls a "super-intelligent" fan base.
