New to the board, hello everyone! I have been thinking that an HBO 10 episode per season series is the best way to bring Jack beyond the novels.
Certainly a movie of The Tomb could be awesome, but this is not the way to go. Think of having the story of the Tomb spread over 10 episodes while giving time for Jack to work on other fixes and explore the mythology of the universe. This would allow enough time to tell the story without dragging it out like it was on network television.
The budget of HBO would also allow for better special effects, the inclusion of flashbacks, violence, adult language, etc. I think it would be awesome.
I just started Harbingers, btw. Infernal was awesome.
