OFF AND RUNNING: Oleanna, the debut production of University of Dallas professor Kyle Lemieux’s Dallas Actor’s Lab, opened recently at the Green Zone. The play deals with a college student who battles with her male professor when she finds herself in danger of failing his course. And from reading the reviews, it sounds as if the new company is a welcome addition. “The two-character play vividly dramatizes the enormous interpretations available in the simplest of language, and most innocent of gestures,” Martha Heimberg writes on theaterjones.com. “Oleanna sets the tone for the kind of theater the Lab seems interested in producing,” Liz Johnstone writes on Front Row. Catch it through Aug. 14.

And now, the Guggenheim Foundation in New York is taking the concept one large step further with the first pop-up museum.
