Perhaps a thread on mainstream Sci Fi authors and their works that were featured in Comics would prove fruitful.
Looks like one of the moderators split this off for you, but just so you know, you're just as entitled to start topics as the rest of us, if you think it'll interest the group. Don't be afraid to color outside the lines a little bit...
Anyway, Bradbury's works were published, I believe, by DC in the '80s under a quasi-imprint they planned to expand mightily but never caught on. If I remember correctly, it was more a line of heavily-illustrated, abridged novels than what we'd call a graphic novel.
Of course, I've never understood the draw of "look, we hired a REAL writer." Probably because I see those types of moves as more strongly enforcing the ghetto (in the isolated Prague sense, not the "down in da 'hood" sense, by the way) atmosphere than breaking it. But that's an entirely different discussion for another time.
More to the point here is that there are many writers who didn't move in one direction or the other, but rather kept a foot in both worlds. Otto Binder (with his brother Earl under the pseudonym "Eando Binder"--E And O, which is kind of cute) and CC Beck both did a fair amount of Pulp sci-fi which is fair to good. Edmond Hamilton is also another Fawcett alum who also spent a bit of time inspiring and writing for DC, but also has a lot of magazine work under his belt.
And even if you didn't know any of that, you've almost certainly heard of the Binders' most enduring creation, Adam Link, an intelligent crime-fighting robot that DC in no way stole for their Robotman character. Totally different, and the fact that the trials that prove their humanity are almost word for word identical is a complete coincidence. (Yes, I know that Robotman has a human brain, and is therefore technically different.) Adam has been portrayed on "The Outer Limits," I believe, and also certainly inspired many characters (directly and indirectly) like Star Trek's Commander Data, who also had to defend his humanity at trial that couldn't possibly be like what the Binders wrote.
Oh, and as I mentioned before, there's Harlan Ellison. I don't think his work made it to the comics, but he did, in the most nonsensical excuse for a Justice League story until the hiring of Brad Meltzer.

Don't listen to the hipster commenters pretending that they "get" the story. They don't. It really is just a story about a jerk throwing a tantrum because a woman dressed like a hooker (well, cigarette girl, technically--go ahead and look it up, if you don't believe me) won't date him.
