>>93191349>What exactly is his role in the DCEU?Generally he's an Executive Producer. That means he's above the Producer (all kinds) and has a quality control role; it also means he spends very little time, if any, on set.
In the case of Mr Johns, he's probably got a special brief to oversee comic-book accuracy and to OK any deviations from the source material, rather than the wider financial or logistical brief of most EPs. He has, however, been working in production roles since the late 1990s, when he took on some work as Co-Producer on Lethal Weapon 4, under Richard Donner. Most of his work since then seems to have been more quality than financial control, however.
You don't need to be in any guild to be a producer - there's no guild for them, in fact - because it's such a nebulous and ill-defined role. Generally, producers do the kind of stuff I've mentioned, but some are what you might call PINOs - producers in name only - who get a producer credit (and therefore their name on the film, sometimes above the line as in, in the credits at the start, as well as at the end). This is usually to keep rubes quiet, but sometimes because someone facilitated the contract that allowed the studio to make the movie (eg buying or selling the rights). If they're going to be allowed any input at all, a producer credit is a good way of keeping the guild professions happy - so your rube can make casting decisions without pissing off the casting director (to a degree).
>Was the success of Wonder Woman due to his influence? No, he had very little input into it. Quality control is not the same thing as creative input.
>Will he effect the Justice League movie?In the same limited way. He's not listed as a writer (not even for a story or character credit) so far as we can tell at this stage, so he's likely just on it in his EP role.
It has been suggested he'll write the now-delayed Batman solo as well as the Green Lantern reboot, but this may not happen.
