Andrew Adamson and writer Joby Harold sold the fantasy-adventure to Lightstream, which is based on an original idea by Joby Harold. Harold is writing the script, which Adamson will direct. Adamson, Aron Warner, Tory Tunnell will produce the film, and Joby Harold will is going to serve as executive producer. The film, which is live-action, has no release date set. Lightstream was founded in 2007.
I’m not sure what the fate is of the previous film that Adamson was attached to, Mister Pip. According to IMDB, he’s still attached to direct that film as well, but it looks like Fountain City could come first.
