E.T. The Extra-Terrestrial (1982) is the immensely popular magical fantasy movie myth. Its estimated budget of $10 million was easily recouped when it became one of the box-office champion films of all time. Steven Spielberg's very personal, heartwarming sci-fi masterpiece (with special effects produced by George Lucas' Industrial Light and Magic Company) was warmly accepted by film audiences for its portrayal of the love between a young, fatherless suburban boy and a lost, benevolent and homesick visitor (presumably an adult) from another planet who is mistakenly left stranded and orphaned on Earth - three million light years from home.
