Also Marvel is thinking of doing something "punisher" again.
So with that in mind I think that Ray Stevenson would be a great choice to play Frank Castle.
Next what I'd love to see is a director who can capture the bleak film-noir atmosphere (in the sense of bleak, cynical outlook, not the sexual motivations) The Punisher has always embodied.
I think David Cronenberg would be a excellent choice, he had demonstrated in his film "A History of Violence" he is capable of capturing believable plots, dismal atmosphere and, at least in that film it amalgamates into a beautiful organic atmosphere.
I want my new Punisher like I want my comedy: bleak, dark, brutal, mature and most of all-believable.
