Avengers: Infinity War will be filmed entirely in IMAX, written by Captain America team

Marvel is going bigger than ever for its third and fourth Avengers movies. The two-part Avengers: Infinity War will be filmed entirely with IMAX cameras, making it the first Hollywood feature film to be shot wholly in the oversized format, IMAX announced today.

Directors Joe and Anthony Russo will use a new camera co-developed by IMAX and Arri to film Avengers: Infinity War — Part I and Part II, and will film a portion of their next movie, Captain America: Civil War, with the same technology.

IMAX CEO Greg Foster told Variety that the Russos "are going to spend the next 15 months or so designing the making of the Avengers films with these cameras in mind," calling the project unprecedented.

Marvel also confirmed today that writing team Christopher Markus and Stephen McFeely will write the screenplay for both Infinity War movies. The pair previously collaborated on Marvel Entertainment's three Captain America movies and created television show Agent Carter.

Earlier today, Marvel confirmed the cast of Captain America: Civil War, which is bursting at the seams with Avengers. Production on that film started today.

Avengers: Infinity War — Part I will be released May 4, 2018, with Part II following on May 3, 2019.
