Avengers 4 is still in production and it is going to be a long wait before it hits cinema halls. Meanwhile, speculation about the upcoming movie is in full swing on the internet. For a very good reason, too, since the fate of half the Marvel Cinematic Universe hangs in balance. Avengers: Infinity War ended with a cliffhanger. Thanos, the primary villain of the Marvel Cinematic Universe, decimated half of universe’s life, including half of the superheroes, all of the newer ones – Black Panther, Doctor Strange, Spider-Man and more.
