Legendary directors tend to become the subject of documentaries near the tail end of their careers, but HBO has chosen to dig into Steven Spielberg’s career now while he is arguably still going strong. Next month they will air a feature-length doc called simply Spielberg and it features extensive interviews with the man himself in addition to conversations with many of his friends and creative partners including George Lucas, Francis Ford Coppola, Martin Scorsese, Daniel Day-Lewis, Brian de Palma, Leonardo DiCaprio, Harrison Ford, Tom Hanks, J.J. Abrams, Drew Barrymore and Robert Zemeckis. It is unclear if there is anything new to be said about his many landmark films but this still seems too tempting to miss. Directed by Susan Lacy (American Masters), Spielberg will air on Sat. Oct. 7th at 8 pm. Check out the trailer after the jump and see what you think.
