Robert Downey Jr. was just five years old when he made his screen debut in a film directed by his father. It was the first credit in a career that would veer from 1980s Brat Pack films like Weird Science and Less Than Zero — and even a brief stint on Saturday Night Live — to an Oscar-nominated turn as Charlie Chaplin, a Golden Globe-winning run on Ally McBeal, and, eventually, the Marvel phenomenon that made him a global superstar.
Downey has always seemed drawn to characters who live close to the edge, and his personal life has followed a similarly dramatic trajectory. Before donning the Iron Man suit, years of substance abuse, arrests, and stints in rehab threatened to derail his career. After getting sober in 2003, he began to rebuild, with Mel Gibson helping secure the insurance bond that made his return to filmmaking possible. What followed was one of Hollywood’s most extraordinary comeback stories: a string of hits that culminated in his casting as Tony Stark, and, in 2024, his first Academy Award for his role as Lewis Strauss in Oppenheimer.
Away from the screen, Downey has channeled his second act into environmental advocacy with the FootPrint Coalition, a nonprofit aimed at supporting and promoting sustainable technologies. In 2024, he also co-wrote the book Cool Food: Erasing Your Carbon Footprint One Bite at a Time with climate advocate Thomas Kostigen, a practical guide to making everyday choices that are kinder to the planet.
To celebrate its release, Downey reflected on five books that made a lasting impact on his life for Oprah Daily. From American Prometheus and the ethical questions surrounding technological advancement to Hacking Planet Earth‘s optimistic vision of what collective action can achieve in the fight against climate change, check out his recommendations below, and explore the bookshelves of other iconic actors here.
Robert Downey Jr.’s Reading List
Julian by Gore Vidal
“Based around the perils of compassionate, intellectual leadership in post-pagan Rome (written largely in the first person), it swept me into an education about an emperor whose reign, although brief, burned bright.” -RDJ
Short Cuts: Selected Stories by Raymond Carver
“In the ’80s, Brett Easton Ellis’s Less Than Zero became a dark and sticky classic, but in the ’90s, Raymond Carver single-handedly revived the American short story. A wickedly funny, surprisingly innocent meditation on loss and tenderness, all nine stories and a poem will give you hope.” -RDJ
American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer by Kai Bird and Martin J. Sherwin
“This one made a difference in my preparation to play Lewis Strauss [in Oppenheimer], his nemesis, but more so as essential reading for anyone who seeks to understand the moral dilemmas J. Robert Oppenheimer faced that are every bit as relevant today as the pending challenge of A.I.” -RDJ
The Sympathizer by Viet Thanh Nguyen
“I grew up in the Vietnam era but never really looked at it from outside my American perspective. This Pulitzer Prize–winning book tells the story of a double agent of mixed heritage who is consistently ‘othered,’ both in his home country of Vietnam and, after the fall of Saigon, in America, where he is embedded as a Communist spy. The Sympathizer taught me that it’s possible to hold several truths in your head and heart, that power will always corrupt, and that self-determination is a prerequisite.” -RDJ
Hacking Planet Earth by Thomas M. Kostigen
“Honestly, Tom K.’s book inspired me to embrace the possibility that there are big-scale solutions for our climate crisis that everyone can contribute to in a meaningful way, that it’s not ‘too late,’ and that if I was lucky, I’d write a book with him one day!” -RDJ
