The Marvel Cinematic Universe as a collective franchise has spawned no less than ten movies to date and there are many more in the offing. As a result, the existing movies drop all kinds of hints and make a point of setting the scene for future instalments, which enables fans to predict - or at least guess - what might happen in those upcoming offerings. Some of these predictions are self-explanatory - the name-dropping of Doctor Strange in Captain America: The Winter Soldier, for example, is a sure-fire sign that the Sorcerer Supreme is coming to the Marvel Cinematic Universe and the constant presence of the Mad Titan Thanos in the background makes his appearance as a main villain in the future an absolute certainty.

Whether or not they will actually go on to happen is completely open to debate, but it's certainly fun to speculate and many of those theories would make things a lot more interesting in the Marvel Cinematic Universe - and that's what we're going to be discussing here. Here are ten awesome fan theories that would make the Marvel Cinematic Universe more interesting...
