It seems that something is coming tonight in the early hours of Tuesday morning. We can't be sure, but a trailer seems likely, or an official release date for the series at the very least.

Rumor has it that another Marvel hero may also appear in The Punisher. It could be a member of the Defenders or a new entry into the Marvel Cinematic Universe. Perhaps a trailer will offer the first clue as to who it could be.

Frank Castle is an ex-Marine and was a family man. That all changed when a botched police operation intended to bring int he weapons dealer known as Blacksmith cost Castle his family. From that day forth Castle has been a vigilante seeking out and punishing criminals wherever he can find them. As the Punisher, Frank Castle uses any means necessary to dish out lethal justice to criminals in New York City.

Marvel's The Punisher is being developed by Steve Lightfoot for Netflix. Lightfoot will serve as showrunner. Marvel's The Punisher is the first series to spin out of one of Marvel's other Netflix shows. Bernthal debuted the role of Frank Castle in the second season of Marvel's Daredevil.

The Punisher is based on the Marvel Comics character created by Gerry Conway, John Romita Sr., and Ross Andru, who debuted in Amazing Spider-Man #129 in 1974. Originally intended as a cautionary Spider-Man villain, the Punisher's relentless, hardline vigilante tactics resonated with certain fans and turned him into a cult favorite. He has since starred in several ongoing series from Marvel Comics and three previous live-action movies: one starring Dolph Lundgren in 1989, another starring Thomas Jane in 2004, and Punisher: War Zone starring Ray Stevenson in 2004.
