E.T. the Extra-Terrestrial is a 1982 American science fiction-family film co-produced and directed by Steven Spielberg and written by Spielberg and Melissa Mathison, featuring special effects by Carlo Rambaldi and Dennis Muren, and starring Henry Thomas, Dee Wallace, Robert MacNaughton, Drew Barrymore and Peter Coyote. It tells the story of Elliott (Thomas), a lonely boy who befriends an extraterrestrial, dubbed "E.T.", who is stranded on Earth. He and his siblings help it return home while attempting to keep it hidden from their mother and the government.

The concept for the film was based on an imaginary friend Spielberg created after his parents' divorce in 1960. In 1980, Spielberg met Mathison and developed a new story from the stalled science fiction/horror film project Night Skies. It was shot from September to December 1981 in California on a budget of US$10.5 million. Unlike most motion pictures, it was shot in rough chronological order, to facilitate convincing emotional performances from the young cast.

Leet (or "1337"), also known as eleet or leetspeak, is an alternative alphabet for many languages that is used primarily on the Internet. It uses various combinations of ASCII characters to replace Latinate letters. For example, leet spellings of the word leet include 1337 and l33t; eleet may be spelled 31337 or 3l33t.

The term leet is derived from the word elite. The leet alphabet is a specialized form of symbolic writing. Leet may also be considered a substitution cipher, although many dialects or linguistic varieties exist in different online communities. The term leet is also used as an adjective to describe formidable prowess or accomplishment, especially in the fields of online gaming and in its original usage – computer hacking.
