The play was also selected by the National Foundation for Jewish Culture on the 350th anniversary of Jewish life in America as a play that "breaks new ground."

Zark's adaptations of two Eric Kimmel books. The Magic Dreidels and The Chanukah Guest were commissioned and produced by the Minnesota Jewish Theatre, which also produced A Body of Water. Zark has also written a number of children's plays for Steppingstone Theatre.

Zark's play The World to Come was originally commissioned and produced as a one-act by the Jewish Women's Theater Project in Los Angeles. The play was then expanded to a full length and recieved a reading at Playwrights Horizons and workshop productions at the Producer's Club in New York.
