The dangling apartment setting of Woolly’s Full Circle.

When it comes to Woolly Mammoth’s season-opening production of Full Circle, sometimes you just have to run with it. Literally.

This is a show where the audience relocates from separate rooms to a central location, from the complex lobby to the main theater. All the movement helps contribute to the chaos in which the show is set – in East Germany, just after the collapse of the Berlin Wall. It’s also, frankly, a lot of fun to move from space to space, wondering what setting Shannon Scrofano has in store for us next (a tightrope bridge suspended across an abyss? A catwalk apartment?). The variety is key in a 2.5+ hour play with moments of pretentious meandering.

Full Circle is most focused on what’s going to happen to the baby of ousted political leader Erich Honecker (a wheezing, sputtering, committed performance from Sarah Marshall) and his mistress (Kate Eastwood Norris, dizzy but enraged) when it ends up in the hands of a self-absorbed socialite and a young would-be revolutionary. The journey puts the pair at the center of the action, and the two performers are fine company – Naomi Jacobson is poised, regal and airy as high-society Pamela, while Jessica Frances Dukes is heartbreaking with a side of crazy as her instant “au pair,” Dulle Griet.
