In 2019, in addition to other projects, Dietz produced Anne: A New Play, a theatrical adaptation of Anne Frank's Diary that examined what would have happened if Frank had lived. It premiered at the Simon Wiesenthal Center at Museum of Tolerance, where a companion exhibit featuring artifacts, photos and documents from Frank’s life was displayed. She also produced The Investigation: A Search for the Truth in Ten Parts—a reading of excerpts from the Mueller Report—starring Annette Bening, John Lithgow, and Kevin Klein which took place at the Riverside Church in New York. Later that year she produced the LA version at the Saban Theater. Titled You Can't Make This Shit Up it featured Larry David, Billy Porter, Sharon Osbourne and Debra Messing (as Donald Trump). It was staged at the Saban Theater in October 2019 as a fundraiser for Barbara Boxer's PAC for a Change.
