Thirty years ago, on the 9th of December 1982, a family movie was released which would be critically acclaimed as a timeless story of friendship. It drew on the real story of director Steven Spielberg's parents' divorce and follows a young boy, Elliot, and his siblings who make friends with a stranded alien and try to help him return home. Henry Thomas, who starred as Elliott, revisits the suburban Californian house where much of the movie was made.
