From Rich Johnston of CBR:
"Garth Ennis, Steve Dillon and Jimmy Palmiotti are working on a prequel to the 'Punisher' movie, which will be inserted in the Punisher DVD when released."
I guess what I don't understand is this: Doesn't the original Punisher film show the origin/backstory for the character? What the heck do you put in the prequel? More scenes from his pre-catastrophe idyllic family life?
Then again, these guys are involved with the actual Punisher comic book, so maybe they'll manage to do something better with the prequel than the actual film...
