1) Thomas And Martha Wayne
Surely the best instance of comic book characters being hidden in a DC movie is this example from Watchmen. Fans of the revisionist superhero movie might be shocked to know that it features none other than Batman’s parents. However, in Watchmen’s world, things went a little differently for the Waynes.
During the amazing opening sequence, which details an alternative 20th century protected by superheroes, one part shows Nite Owl saving a rich couple from an armed criminal. It can be seen that they have just come out of Gotham Opera House which was showing something called “Fledermaus.” Can anyone guess what this means in German?
In case that wasn’t enough of a hint, there are also several posters of what in the real world is the cover to Batman #1, but in Watchmen’s world is presumably a poster for a movie.
As the film proves, the Watchmen might not have been the most successful superheroes but hey, at least they saved the Waynes. Even Batman couldn’t do that (sorry, Bruce).
