Larklight is the first book in a series by Phillip Reeve with illustrations provided by David Wyatt. The story is set in an alternate Victorian-styled universe where since the time of Sir Isaac Newton, humanity has been relentlessly exploring the solar system. The protagonists are Arthur Mumby (called Art), his sister Myrtle and their father Edward. The three live in a rambling mansion called Larklight and in the first book of the series, the three get into a series of scrapes with giant spiders from outer space.
Hopefully Larklight is going to fare a little better in theaters than other similar projects that have come before it. But I guess that as long as there aren't hidden atheist messages in the story, I'm sure the movie will do just fine. I guess WB is counting on it because the film is going to have a size-able price tag of $200 million. Larklight is still in development, but Kapur has to finish up work on a couple of projects (including taking over for Anthony Minghella in New York, I Love You) before he can start working on Larklight full time.
