It’s difficult to describe the storyline of Adam Bock’s A Small Fire without spoilers, since the medical crisis experienced by the play’s matriarch (Tony winner Michele Pawk) packs such a dramatic punch. But the classy cast of Playwrights Horizons’ world premiere production—Pawk, Tony nominee Celia Keenan-Bolger, Reed Birney and Victor Williams—gave it a go in a video preview feature with Broadway.com. Bock, whose plays include The Receptionist, The Drunken City and Swimming in the Shallows, also weighs in on the themes explored in his thought-provoking family drama.
