Jessica Chastain and the Work Behind Her Oscar
Training and a Breakthrough in Film
Born in Sacramento, California, Chastain graduated from Juilliard in 2003. Her early career included stage performances and television appearances before her film work brought wider recognition. In 2011, she appeared in The Tree of Life, Take Shelter, and The Help, giving audiences several introductions to her acting within a single year.
The Help earned Chastain a supporting actress Oscar nomination in 2012. Her next nomination came in the leading actress category in 2013 for Zero Dark Thirty. Moving between an ensemble period drama and a thriller centered on an intelligence analyst established her ability to carry very different kinds of stories.
Bringing Tammy Faye to the Screen
Chastain won the Academy Award for best actress in 2022 for The Eyes of Tammy Faye, a film released the previous year. She portrayed televangelist Tammy Faye Bakker and also served as a producer. That second role placed her among the people responsible for getting the project made.
“And I’m inspired by her compassion and I see it as a guiding principle that leads us forward.” — Jessica Chastain, speaking about Tammy Faye in her 2022 Oscar acceptance speech.
Her speech connected the performance to acceptance and compassion, including support for LGBTQ people. It offered an explanation of what she valued in the character beyond the makeup and mannerisms that made Tammy Faye instantly recognizable.
Building Freckle Films
Chastain founded Freckle Films in 2016 to create opportunities for women in the entertainment industry. The company focuses on stories with women at their center and characters whose experiences have received less attention on screen.
Its slate includes the action film The 355 and the television drama George & Tammy. Through the company, Chastain participates in developing material as well as performing it. Producing extends her involvement to decisions about which stories receive resources and reach an audience.
Mike Krieger and the Products He Helped Build
From Stanford to Instagram
Krieger moved from Brazil to the United States to attend Stanford University, where he earned undergraduate and master’s degrees in symbolic systems. The subject brings together disciplines including computer science, psychology, linguistics, and philosophy. It examines human thought and computation, combining technical study with questions about how people understand and communicate information.
In 2010, Krieger co-founded Instagram with Kevin Systrom and became its chief technology officer. His work involved building the engineering organization and helping the service operate as its audience expanded. During his tenure, Instagram grew to more than a billion users, and its engineering team reached more than 450 people.
Those responsibilities extended well beyond the design of a photo-sharing screen. Supporting a service at that scale requires the systems behind it to handle increasing activity while engineers continue developing the product. Krieger’s experience combined that technical work with leadership of a growing team.
Artifact and a Move Into Artificial Intelligence
Krieger and Systrom later created Artifact, a news discovery app that used artificial intelligence to personalize recommendations. Yahoo acquired it in April 2024. The acquisition was intended to bring Artifact’s technology into Yahoo’s products, including Yahoo News, rather than preserve it as a separate app.
Anthropic announced Krieger’s appointment as chief product officer on May 15, 2024. His responsibilities covered product engineering, product management, and design, with a brief to expand access to Claude and develop the company’s enterprise applications.
“The potential for AI to positively impact the world is immense.” — Mike Krieger, in the announcement of his move to Anthropic in May 2024.
His role changed in January 2026, when Anthropic announced that he would join its Labs team to build alongside Ben Mann. Ami Vora took leadership of the Product organization. Labs focuses on experimental products, testing new possibilities for Claude before promising ideas are developed for wider use.
