In the trailer, we see him pounding a sledgehammer into what looks like solid cement, revealing the Punisher's trademark skull icon. (John Wick would approve.)
Over flashbacks to Castle's tragic past, we also hear brief narration that promises several violent showdowns: "The past is more than memories, it's the devil you sold your soul to. He's coming to collect."
Netflix hasn't yet set an official release date for the series, although IGN reports it will likely debut this November.
