Joaquin Rafael Phoenix ( born October 28, 1974), formerly credited as Leaf Phoenix, is an award-winning American and Puerto Rican film actor. He is from a family of performers and is the younger brother of late actor River Phoenix.

Phoenix has ventured behind a camera, directing music videos as well as producing movies and television shows, and has recorded an album, the soundtrack to Walk the Line. He is also known for his work as a social activist, particularly as an advocate for animal rights.

Family background and early life

Phoenix was born Joaquin Rafael Bottom in Río Piedras, located in the city of San Juan, Puerto Rico. He is the third of five children, including the late River (1970 – 1993), Rain (1972), Liberty (1976), and Summer (1978). He also has a half-sister named Jodean (1964), from his father's first marriage.

His father, John Lee Bottom, was a lapsed Catholic from Fontana, California. His mother, Arlyn Phoenix (née Dunetz), was born in the Bronx, New York to Jewish parents from Hungary and Russia. In 1968, Arlyn left her family and moved to California, later meeting Phoenix's father while hitch-hiking. They married in 1969, then later joined the religious cult the Children of God. They began travelling throughout South America.

His parents eventually became disillusioned with the Children of God; they made the decision to leave the cult and returned to the U.S. in 1978. They changed their last name to "Phoenix" to symbolize a new beginning. This was also around the time Joaquin had begun calling himself "Leaf", desiring to have a similar nature-related name like his siblings (he was inspired by spending time outdoors raking leaves with his dad). This is the name he would use as a child actor; at fifteen, he changed it back to 'Joaquin'.

In order to provide food and financial support for the family, the Phoenix children performed on the streets and at various talent contests, singing and playing instruments. In Los Angeles his mother started working as a secretary for NBC, and his father worked as a landscaper. Joaquin and his siblings were eventually discovered by one of Hollywood's leading children's agents, Iris Burton, who got the five children acting work, mainly doing commercials and television show appearances. Phoenix went on to establish himself a child actor before deciding to withdraw from acting for a while and travel to Mexico and South America with his father.

Phoenix came back into public view under tragic circumstances: on October 31, 1993, his brother, River Phoenix, suffered a fatal drug overdose, outside the famed Hollywood nightclub The Viper Room, which was owned by Johnny Depp. Joaquin's call to 911 to save his brother was recorded and repeatedly played over the airwaves and on television. The sudden media intrusion into his life proved to be too overwhelming; once again, he retreated from the public eye. A year later, at the insistence of his friends, Joaquin reluctantly re-entered the world of acting.He is of Hungarian and Russian descent.
