Late Night, originally written by Sandler for the 24-hour playwriting contest at the Toronto Fringe, was produced in 2016 by Moses Znaimer of ZoomerMedia.

Yaga, a reimagining of the myth of Baba Yaga, debuted at the Tarragon Theatre in 2019, starring Seana McKenna in multiple roles, including a university professor with "a taste for younger men".^[16] The story blends folklore with a whodunit, following a detective investigating the disappearance of a student who interviewed the professor about Baba Yaga.^[17] Sandler adapted the play into a television series of the same name for the Canadian streaming service Crave, and she was also the showrunner for production in 2026.^[18]
