“Avengers: Endgame” was one of the biggest films of 2019, earning more than $1 billion at the box office.

The film – a culmination of a decade of Marvel movies – featured time travel, heartbreaking moments, and a major battle sequence.

Larger-than-life moments were made possible through the use of computer-generated imagery, or CGI, and other special effects. And often, the most exciting scenes in the movie were filmed in front of a green screen.

In a new video shared by Marvel Entertainment, the “Endgame” visual-effects supervisor Dan DeLeeuw broke down the film’s major battle sequence with Ryan Penagos.
