Spielberg was born on December 18, 1946 in Cincinnati, Ohio. His family was Orthodox Jewish. Spielberg's paternal grandparents were Jewish Ukrainian immigrants who settled in Cincinnati in the 1900s; his grandmother was from Sudylkiv, while his grandfather was from Kamianets-Podilskyi.

As a child, Spielberg faced difficulty reconciling being an Orthodox Jew with the perception of him by other children he played with. Spielberg also said he suffered from acts of anti-Semitic prejudice and bullying: "In high school, I got smacked and kicked around. Two bloody noses. It was horrible."

At age 12, he made his first home movie: a train wreck involving his toy Lionel trains. Throughout his early teens, and after entering high school, Spielberg continued to make amateur 8 mm "adventure" films.

While still a student, he was offered a small unpaid intern job at Universal Studios with the editing department. He was later given the opportunity to make a short film for theatrical release, the 26-minute, 35 mm, Amblin', which he wrote and directed.

Studio vice president Sidney Sheinberg was impressed by the film, which had won a number of awards, and offered Spielberg a seven-year directing contract. It made him the youngest director ever to be signed for a long-term deal with a movie contract.
