Welcome to the board Dave and Dan!!
Hope you guys give a role to Avery Clark,our resident actor on the board here, and fan of the series.
Please send a script to Benicio Del Toro, for the role of the Red Viper, maybe he is a fan of the series, and will do it for less then he would one of his films. I would think any actor would love to play some of these well written characters.
Best of luck what every you guys decide. I write to HBO periodically, reminding them of the fan base out here, that wants to see this done.
Not sure if they read it, or take it in any consideration or not though.
