10 Movie Secrets That Were Hiding In Plain Sight

1. Thor Not Being The First Born - Avengers: Age Of Ultron

Thor's nightmare in Age of Ultron turned out to be a pretty iffy scene in the grand scheme of things, as while the prophecy of the end of Asgard did come into play, Thor Ragnarok's apocalyptic narrative didn't really reflect this scene. That said, it's still an important part of the franchise for one reason: it actually revealed that Thor wasn't Odin's first child.

While interacting with a crazed Heimdall, Thor is referred to as the "first son of Odin", rather than his "first born" or first child. While that could just be strange phrasing, it could also be a reference to the fact that while Thor was indeed Odin's first son, the Goddess of Death, Hela, was eventually revealed to have been born before him.

Whilst it's easy to brush that off as reading too much into the text, there's no denying how much Marvel was relying on this scene to set up future movies, forcing Joss Whedon to include it in the final cut despite it being a pretty major tangent.

It was meant to be purposefully mysterious and tease the future of Thor's journey, so it would make sense that Marvel would seed the eventual Hela revelation so far in advance.
