Christopher Abbott and Amanda Seyfried Cast in Roles of Billy Evans and Elizabeth Holmes

Christopher Abbott plays Billy Evans and Amanda Seyfried plays Elizabeth Holmes in You Can See Everything, the film made by Nathan Fielder and Lance Oppenheim. The Hollywood Reporter reported the casting on 14 November 2026.

Holmes is the former founder of Theranos, the blood-testing company. She was later sent to prison. The two actors were brought in to recreate the filmmakers' interactions with Holmes and Evans. Those scenes include moments that happened off camera, and some that took place after Holmes was imprisoned.

Abbott told The Hollywood Reporter, at an event for the television series East of Eden, that Fielder and Oppenheim called him and asked him to come mess around. He had seen some of the footage the pair had shot before he took part. He said he did not really know who Billy Evans was until the filmmakers showed him that material.

Zoe Kazan, a co-showrunner of East of Eden, said she did not know Abbott was in the film until she saw him on screen in a cinema. That is a small detail, but it shows how little the casting was announced ahead of release.

For a film built around real people, the choice to cast actors in the key roles adds a second layer. Viewers will be watching performers play figures who were there in the room, on and off camera, during events the filmmakers chose to revisit.
