Because some folks do NOT follow the "Avengers" movie franchise, IMO, you could watch each installment as a stand alone as the films have been great about giving enough general backstory about the heroes and not obvious Good/Bad guys to enjoy the movie in theatres!
However, if you are game for getting your heart trampled on by the time "Avengers: Endgame" hits theatres in April of next year, here are previous movie trailers to whet your appetite!
"Avengers: Age of Ultron" was released in 2015.
In 2008, the film and character that kicked off the modern film era of what is known as the Marvel Universe was the Robert Downey, Jr. lead "Iron Man".
Earlier this year, three films were released in quick succession: "Black Panther", "Avengers: Infinity War" and "Ant-Man and the Wasp".
Below is the movie trailer for "Infinity War"...
As time has gone on, the films have been more humorous and always action-packed, amazing casting, costuming, editing...the Marvel Universe is truly fun to jump into!
Will you be playing catch up over the holidays and enjoy All the past movies ahead of April 2019?
