Due to a prior commitment, Heck's final performance will be Feb. 3. Coffey starts performances on Feb. 5 through the end of the extended run on Feb. 10.

Heck plays part of a wide community of drug addicts seeking support, and connecting to the core family of the ensemble drama by Quiara Alegría Hudes. Davis McCallum directs.

Water By the Spoonful also stars Liza Colón-Zayas, Frankie R. Faison, Zabryna Guevara, Sue Jean Kim, Armando Riesco and Ryan Shams.

In the play, according to Second Stage, "Elliot returns home to Philadelphia to reconnect with his Puerto Rican family after his time spent serving in Iraq. Upon arriving, he finds his family in flux and his career prospects limited. When an online support group begins to overshadow his aspirations for the future, the real and online worlds — one forged by blood, another by survival — collide in this funny, urgent and timely 2012 Pulitzer Prize winner."

Water By the Spoonful is the second in a trilogy of plays that began with Hudes' Elliot, A Soldier's Fugue, a play about a young Marine coming to terms with his time in Iraq and his father and grandfather’s service in Vietnam and Korea. The third play in the trilogy, The Happiest Song Plays Last, is scheduled to make its world premiere in April at The Goodman Theatre in Chicago.

Coffey appeared in Richard Nelson's Frank's Home (Playwrights Horizons & Goodman Theatre), How Shakespeare Won the West (Huntington Theatre), Arthur Miller's Resurrection Blues (Old Globe), The Front Page (Long Wharf Theatre) and more.
