At the center of the excellent six-person cast is Paco Tolson as Semyon (and a few other characters); he's a terrific everyman, at once put-upon and swaggering, vain and frightened out of his gourd. William Jackson Harper is sensationally good as Gran-Skubic and Curran Connor is deliciously slimy and vaguely malevolent as Semyon's neighbor Kalabushkin (both Harper and Connor also take a few other roles, too). Aaron Roman Weiner is very funny in a variety of guises—the butcher, clad in a blood-encrusted apron; the meek mailman who believes in the Cause, whatever the cost; and a decrepit old woman who lives in Semyon's building. Tami Stronach and Cindy Cheung show their versatility by each playing one of the glamorous actresses and also Semyon's drudge-like wife and mother-in-law (again, among other roles).
And here's to Robert:
The show's pace is fast and furious and the fourth-wall-breaking moments, which include most notably live sound effects played by whichever member(s) of the ensemble aren't needed for a particular scene, are great fun. If you think thought-provoking theatre that's literally about important issues like life and death, economics, politics, and the social contract can't be wildly entertaining, well, here's Robert Ross Parker to prove you wrong.
