Al K. (Beyond The Black Gate) is currently writing a Warriors Of The Red Planet RPG, based on the Martian series by Edgar Rice Burroughs, with Thomas D. (Original Edition Fantasy) providing the illustrations. I'm really looking forward to seeing this game published!
Trey over at the the blogsite From The Sorcerer's Skull posted a picture of Valerie Leon from the 1971 Hammer horror film Blood From The Mummy's Tomb. He joking commented, in a later post , that she would be great as Dejah Thoris, Princess of Mars. She certainly had the presence for it.
I love Thomas D.'s interpretation of Dejah Thoris. If you visit his OEF blog, you will find an action figure he posted, and couple of Dejah Thoris illustrations he created, here and here. The first illustration gives Dejah Thoris a very haughty appearance, which is appropriate, all things considered. I prefer the second, however, as it makes her appear very vulnerable.
