It's been called "Australia's Spotlight". A film about a landmark sexual abuse case for damages against an Anglican school is being shot in Queensland, with an impressive cast headed by Rachel Griffiths, Jack Thompson, Aden Young and Jacqueline McKenzie. 
Director Tori Garrett describes Don't Tell as a a "riveting" courtroom drama telling an important story that triggered new regulations and contributed towards the creation of the Royal Commission into Institutional Responses to Child Sexual Abuse.
"The material is so strong," Garrett says. "The stuff we're talking about in the courtroom is straight from the court transcripts, so it's all word for word true."
Don't Tell is based on a book by lawyer Stephen Roach (Young), who represented 22-year-old Lyndal (Sara West) when she took action against Toowoomba Preparatory School in 2001.
The school denied she had been sexually abused by a boarding house master, played by Gyton Grantley, a decade earlier. As a result of the case, the Anglican Archdiocese of Brisbane paid her compensation of more than $800,000.
Griffiths plays a psychologist who counselled Lyndal, with Susie Porter and Martin Sacks as her parents, Thompson and McKenzie as barristers and Kim Knuckey as Archbishop Peter Hollingworth. Missy Higgins is working on a song for the film.
Garrett says the film tells a very different story from Spotlight, which won best picture at the Oscars recently.
"Ours is a survival story about a little girl and the courage she had to try and stop it happening," Garrett said.
"It's based on a similar theme - child sexual abuse - but it's a different story altogether."
