I was curious about Katuman, so I looked him up on the net. And, Yes! He shows up again, later, in other Conan tales. Evidently, he's in a story arch staring with Marvel's Conan The Barbarian Issue 247. He appears in several issues. That same story arch also features Red Sonja and Zula.
The appearance of Katuman in Conan The Barbarian Issue 247 belongs to the readaptation of Black Colossus by Roy Thomas.
Really? Looking at THIS SOURCE, it looks to be a story told along side Black Colossus, not a readaptation. It speaks of Conan, Red Sonja, and Zula encountering Katuman and a Stygian Black Ring sorceror named Shu-Onoru.
I haven't read the story yet, but it looks like it involves Katuman and a Shemite city-state named Yamman, led by King Irruk.
The story arch starts in 247 and goes through 250, four issues. My guess is that Black Colossus happens sometime in those four issues, but so do other stories, not unlike the multi-issue War of Tarim story-line.
Dredd, the new remake starring Karl Urban. It's low budget, and thus, depicts a lower tech world than the comics. But, I'll be danged if the director and his crew didn't nail the character and atmosphere right on its head. This thing's got some atmosphere!
It feels like what I and my buddies would call a "good scheeet flick". "Scheeet" is the brown stuff that dogs drop in lawns. Not a great, fantastic movie, but a low budget film done well.
John Carpenter's films were the original sheeet flicks, in the 80's, to me and my friends. Escape From New York. They Live. Starman. Those are the ones I remember. Low budget films that, for whatever reason, I really enjoyed. Later came other films, like Enemy Mine and Imposter.
And now, Dredd takes its place among those other well done low budget films.
I think that it would translate extremely well to a cable TV series.
If you take it for what it is, you'll probably enjoy it.
So...the Vulcan sect uses transporter and holodeck technology to look into the past, making their tests about changing the timeline. Through this, we experience shows actually set on the destroyed Vulcan homeworld. Digging through old ruins. Learning Vulcan culture.
