The Panama Papers were leaked documents that showed how Mossack Fonseca, a Panamanian law firm, allowed the wealthy and the connected to funnel money illegally in and around the world.

The documents contain personal financial information about wealthy individuals and public officials that had previously been kept private. While offshore business entities are legal, reporters found that some of the Mossack Fonseca shell corporations were used for illegal purposes, including fraud, tax evasion, and evading international sanctions.

Michael Sugar, Lawrence Grey, Gregory Jacobs, Soderbergh and Burns are producing.

Streep will next be seen returning to her role as Donna Sheridan Mama Mia: Here We Go Again in which Lily James will play her younger self.
