Robert John Downey Jr. (born April 4, 1965)[1] is an American actor. His films as a leading actor have grossed over $14 billion worldwide, making him one of the highest-grossing actors of all time. Downey's career has been characterized by some early success, a period of drug-related problems and run-ins with the law, and a surge in popular and commercial success in the 2000s.[2] In 2008, Downey was named by Time magazine as one of the 100 most influential people in the world. From 2013 to 2015, he was listed by Forbes as Hollywood's highest-paid actor.

At the age of five, Downey made his acting debut in his father Robert Downey Sr.'s film Pound in 1970. He subsequently worked with the Brat Pack in the teen films Weird Science (1985) and Less than Zero (1987). Downey's portrayal of Charlie Chaplin in the 1992 biopic Chaplin received a BAFTA Award. Following a stint at the Corcoran Substance Abuse Treatment Facility on drug charges, he joined the TV series Ally McBeal in 2000, and won a Golden Globe Award for the role. Downey was fired from the show in 2001 in the wake of additional drug charges. He stayed in a court-ordered drug treatment program and has maintained his sobriety since 2003.

Downey made his acting comeback in the 2003 film The Singing Detective, after Mel Gibson paid his insurance bond because completion bond companies would not insure him.[3] He went on to star in the black comedy Kiss Kiss Bang Bang (2005), the thriller Zodiac (2007), and the action comedy Tropic Thunder (2008). Downey gained global recognition for starring as Iron Man in ten films within the Marvel Cinematic Universe, beginning with Iron Man (2008), and leading up to Avengers: Endgame (2019).
