Ethan Slater, who starred in the Broadway-bound Spongebob musical when it debuted in Chicago last year, has joined the cast of the Off-Broadway return of Baghdaddy. Formerly titled Who’s Your Baghdaddy?, the musical comedy will begin performances April 6 ahead of a May 1 opening at St. Luke’s Theater.

Set in a church basement, Baghdaddy is centered on a support group for those who started the war with Iraq. The show received critical acclaim when it debuted Off-Broadway in 2015, and is currently scheduled to play a return engagement through June 18.

Slater joins the previously announced Brennan Caldwell (Urinetown), Jason Collins (Signs of Life), Bob D'Haene (The Three Times She Knocked), Brandon Espinoza (Tuck Everlasting), Joe Joseph (Kiss of the Spiderwoman), Olli Haaskivi (Orange is the New Black), Claire Neumann (Triassic Parq), and Larisa Oleynik (Mad Men).

Based on a screenplay by J.T. Allen, Baghdaddy is created by Marshall Pailet and A.D. Penedo, with direction by Pailet. The production will feature musical direction by Rona Siddiqui, orchestrations by Charlie Rosen, and choreography by Misha Shields.

The creative team is rounded out by set designer Caite Hevner, lighting designer Jennifer Schriever, costume designer Summer Lee Jack, and production stage manager Courteney Leggett. Daryl Eisenberg did casting, Edmund Gaynes is general manager, and Sean Springle is the company manager.
