While there is still no release date, Nicole Kidman’s production company Blossom Films announced several years ago that they were adapting Andrew Bovell’s play Things I Know to Be True (2016) into a drama series. Given that Bovell’s play Speaking in Tongues (1996) was adapted so successfully into the film Lantana (2001), this could prove the best place for the material. The play as it stands is good – patchy, perhaps, but richly emotive and deeply considered – but it may benefit from a more episodic and visually dynamic approach. This production at Theatre Works, its Victorian première, fails to paper over its cracks; it even introduces some new ones of its own.
