1/ I got work with DC before Alan did but we had so much enjoyed working together at 2000AD that we decided to pitch a couple of series to DC to work on together. Martian Manhunter was the second; a dark tale of small-town, Cold War style paranoia. Basically, there were rumours and scares about an alien having crash-landed that the local authorities were investigating. Their chief investigator was Detective John Jones, newly arrived from out of state. Of course, only he and we knew it was Mars he’d really arrived from. Alan wrote an outline and I did a few moody sketches.
2/ I mentioned it to DC and was told that J’Onn J’Onzz had already been promised to someone else. In the end, that eventually became Jemm, Son Of Saturn.
3/ Before Manhunter From Mars we’d come up with a sprawling DC multiverse-wide mystery epic featuring the Challengers Of The Unknown. I didn’t even get as far as sketches before we were told that, yes, Challengers had been promised to someone else.
Nobody at DC had even read these proposals but, on seeing Alan’s work in 2000AD & Warrior eventually offered Alan Swamp Thing. I worked out my notice on Green Lantern and then the stars were perfectly aligned for Watchmen…
Thanks for the question, caller, and enjoy your dinner!
