The production cast and crew of "Avengers" 3 and 4 may have given Marvel fans a few spoilers for the last two chapters of the saga, and what is more amazing is, it came from the most unlikely source imaginable.

Filming for both movies have recently concluded, and directors Joe and Anthony Russo decided to celebrate the accomplishment by treating the crew to a giant cake, which was designed based on the movie's chief antagonist Thanos. The brothers also decided to share the confection with the world via twitter, which resulted in fan theories flooding the internet.

While it definitely looks like a harmless and unassuming piece of dessert at first glance, the design itself says otherwise.

The mad titan can be seen atop the cake while holding two of the six infinity stones that will be the central focus of the movie. Holding Thanos aloft are four arms, three of which are very familiar: Black Widow, Captain America, and possibly, The Incredible Hulk.

This leads to speculations from fans that the heroes included in the cake are the ones that are going to die in the movie, as death is also a central theme in "Infinity Wars." The arms are symbolically placed beneath the villain and seem to be depicted at coming out of the ground, which is never a good sign when it comes to being alive.

There are also other speculations that the arms symbolize those who are going to survive by the end of infinity wars, although the former theory is probably closer to reality.

Either way, if the movie does follow the "Infinity Wars" storyline from the comics, it's almost certain that not everyone will make it out alive.

Avengers: Infinity War will be hitting the theaters on May 4, 2018, after Black Panther this February.
