I'm back to the whole time-travel-market-is-soft thing. I present further proof it is not:
Spike Lee has signed on to direct Time Traveler, a movie based on Ronald Mallett's memoir Time Traveler: A Scientist's Personal Mission to Make Time Travel a Reality. The memoir tells the tale of a young African-American male raised in poverty, his journey to becoming a distinguished theoretical physicist, and his obsession to travel back in time to save the father he lost when he was ten years old.
Lee says, "It's a fantastic story on many levels and (also) a father and son saga of love and loss."
Universal Pictures has a time travel thriller in the works called The Archive. David Auburn, who scripted The Lake House for Warner Brothers, will join forces with Walk the Line director James Mangold.
Lastly, I found this fascinating short documentary by Jay Cheel called Obsessed and Scientific. In it, the world-renowned theoretical physicist Michio Kaku offers a very accessible interpretation of time travel. We also meet Larry Habner, an entertainment lawyer who represents the family of John Titor, an alleged time traveler from the year 2036, and Rob Niosi, a man obsessed with recreating a full-scale replica of H.G. Well's time machine. It's a fantastic look at the bizarre crossroads between real scientific theory and science fiction. (run time: 25 min.)
