On the surface, Christopher Durang's one-act play "Mrs. Sorken" and David Mamet's one-act "The Duck Variations" appear to have little in common. In the former play, a middle-aged suburban woman must deliver a lecture on the importance of theatre, but has lost her notes. She decides to just wing it, with scattershot results. Mamet's play features two elderly men on a park bench discussing how the world works and humanity's part in it, all while using the ducks in the pond before them as conversational props and living examples of their theories. Both plays deal with people trying to navigate life's big issues, using the mechanics of theatre to show their work. Mustard Seed Theatre presents Mrs. Sorken and the Duck Variations as a double feature at p.m. Thursday and Friday and 2 and 8 p.m. Saturday and Sunday (January 25 through February 10) at the Fontbonne University Fine Arts Theatre (6800 Wydown Boulevard; 314-719-8060 or www.mustardseedtheatre.com). Tickets are $20 to $25.
Thursdays-Sundays. Starts: Jan. 25. Continues through Feb. 10, 2013
