Cassavetes was born in New York City,^[2] the son of Greek-American actor and film director John Cassavetes and actress Gena Rowlands.^[1] As a child, he appeared in his father's film Husbands (1970). After spending so much of his youth surrounded by the film industry, Cassavetes initially decided he did not want to go into the field. He instead attended Syracuse University on a basketball scholarship, but after an injury effectively ended his athletic career, he decided to rethink his aspirations, ultimately deciding to attend his parents' alma mater, the American Academy of Dramatic Arts in New York.^[3]

He has appeared in the films Face/Off, The Wraith, Life, Class of 1999 II: The Substitute, Backstreet Dreams and The Astronaut's Wife, among others.^[1] He has directed several films, including John Q, Alpha Dog, She's So Lovely, Unhook the Stars, The Notebook, and My Sister's Keeper.^[1] He also adapted the screenplay for Blow^[3] and wrote the dialogue for the Justin Timberlake music video "What Goes Around...

In 1985, Cassavetes married Isabelle Rafalovich.^[8] They had two daughters together before divorcing. Sasha was born with a heart defect and underwent substantial surgery; Cassavetes' film John Q. was dedicated to Sasha, and his later adaptation of My Sister's Keeper was based in part on Sasha's medical experience.^[9]
