Marvel Studios has officially began production on Avengers: Infinity War and what a better way to announce it than a behind the scenes video.  Robert Downey Jr. and more are seen in this video including Chris Pratt who plays Starlord and Tom Holland who is Spider-Man.  That's right this film is going to be huge as most of the Marvel Cinematic Universe will appear in the film and in the video producer Kevin Feige reveal that the Avengers will meet the Guardians Of The Galaxy.  This film will be an epic total blast from the sound of things. Avengers: Infinity War arrives in theaters in May 2019 with production expected to take most of the year and directed by the Russo brothers with it's untitled sequel due in 2020.
