Actress Toni Collette has optioned rights to Isabelle The Navigator, the latest novel from fellow Australian Luke Davies, according to the Sydney Morning Herald. She is expected to produce the film with a friend, short film-maker Sally Chesher. It is not yet known whether she will take the role of the title character.
