18. Blaze Comics
Even before Man Of Steel came out, fans were being wowed by Zak Snyder's attention to detail and his commitment to celebrating the wider DCU in the various nods and references in the film. In the third trailer for the film, there was a very brief sighting of a Blaze Comics logo on a billboard in the background of the face-off between Zod and Superman. This of course nods towards Booster Gold, a sometimes member of the Justice League, who travelled from the future and used self-promotion as a means to boost his fame - including by releasing a comic book under the Blaze imprint. Maybe we'll get to see a future Booster Gold movie? Chances are, this is probably just a jokey reference, but it's a smart one all the same.
