It's pretty much an honourable mention, but in the same vein as Daredevil's motion poster, Netflix's announcement teasers were dotted with Easter Eggs. The most immediate is the inclusion of the Avengers Tower in the background of the poster, despite the fact that it's conspicuously absent from the skyline throughout the show. It must have been an expense too far. Anyway, the poster (and indeed the first teaser) also heavily references the cover art of Jessica Jones artist David Mack, which also influences the aesthetic of the opening credits of the show. That watercolour style also feels like it bleeds into the show's entire moody, noirish look. And wait... who is that ripped figure bathed in red light shadow-boxing in one of the windows in the opening credits? Could it be...?
