From Adrian Wassel: Yeah, sure, there's some truth to it. But you're not going to find any real editors out there who will greenlight comics like this. Comic fans have the very best bulls**t detectors.
No. Do not do exact likenesses without consent/credit. That's a big no-no. That said, artists use celebrities, and friends, and figurines for reference all the time and that's great.

From Adam: I think there are comic artists that have an eye toward optioning, absolutely. For me, if it were to ever happen, great, I would gladly accept all the riches that come, but I am in this 100% to draw. That’s all I’ve ever needed. I would just want to keep drawing. If a live action anything was made from something I worked on, I don’t think I would care and would probably not watch it as it wouldn’t be my drawings, or anybodies drawings.

From John: I don’t doubt that there must be people out there somewhere with the idea of making comics as a shortcut to film and TV glory. But that’s not me, and it’s not any of the comic creators I know. My personal inclination is that, if you’re not in comics because you love comics, you’ll burn out pretty quickly when faced with the actual realities of making comics.
As far as likenesses go, I think my good friend Alex Cormack, artist of SINK and THE CRIMSON CAGE, has a great balance for this. Sometimes, when we're riffing on the appearance of a character, he'll ask me who I would imagine playing them in a movie. Then, he'll draw that person, not using any reference, but from memory. Which means that the design we end up is someone who evokes the general spirit or aura of that person while still being their own distinct design rather than just being based on their likeness.
