Amazon is getting into business with “Avengers: Infinity War” directors Anthony and Joe Russo aka the Russo Brothers, on a “large-scope, multi-layered international event series,” the streamer announced at the Television Critics Association summer press tour Saturday.

“The Russo Brothers have impacted the pop culture barometer of creative excellence with their vision for both ‘Avengers: Infinity War’ and ‘Captain America: Civil War,'” head of Amazon Studios, Jennifer Salke, told reporters. “They brought a level of scale and execution to those films that has raised the bar for audiences everywhere and we can’t wait for them to do the same for us on this project for our Amazon Prime Customer. We are thrilled to be working with Joe and Anthony Russo and their AGBO Studios as they build this incredible, multifaceted, international franchise.”

While no IP is currently attached to the project, Amazon says “the origin mothership series will function as a fire-starter to ignite the creation of multiple original local language and local production series” which are “meant to enhance the entire entertainment experience and will be available for the viewer to deep dive into an imagined layered world.”

The Russo Brothers’ AGBO Studios will produce the currently-untitled project, giving the siblings the “creative freedom to oversee an ambitious concept meant to captivate the Prime Video audience and redefine the boundaries of storytelling.”

Anthony and Joe Russo have sat behind the camera together for the Marvel Cinematic Universe films “Captain America: The Winter Soldier” (2014), “Captain America: Civil War” (2016) and, most recently, “Avengers: Infinity War” (2018). They are currently working on the untitled fourth installment in the “Avengers” franchise, set for a 2019 release.

On the small screen, the Russo Brothers are known for directing episodes of Mitch Hurwitz’s quirky comedy “Arrested Development” (a gig for which they won an Emmy) and Dan Harmon’s “Community.”
