Sanity Productions is a theatre production company based in Darwin, Australia led by Kate Wyvill.

Kate is a  playwright, actor, director and producer.

Following on from the sell-out success of  her black comedy The Wardrobe in 2010 at the Darwin Entertainment Centre , Kate's next script Marbles based around voluntary euthanasia and Alzheimer's drew capacity audiences to Brown's Mart Theatre, Darwin with the  final  curtain coming down on the 30th  November 2012 to a standing ovation. Marbles will have its Sydney premiere in 2018, produced by Crying Chair Theatre. Kate’s latest script, And I'm the Queen of Sheba will open in Darwin in 2019.
