Joining the previously announced Eddie Izzard, Victoria Hamilton and Dana Ivey will be Margaret Colin, Michael Gaston and Madeleine Martin.

The design team features Es Devlin (sets and costumes) and Adam Silverman (lighting).

A Day In the Death of Joe Egg centers on a couple's handicapped child — with the title reflecting the 10-year-old's nickname. The parents concoct imaginary conversations and personality traits for the invalid as their relationship grows more and more strained.

Izzard and Hamilton will repeat the roles they played in the production at London's Comedy Theatre. Joe Egg was booked by the Roundabout after their production of Our Town was canceled. Joe Egg marks the Broadway debut for Izzard. The British comedian-actor, who often dons drag, has visited New York in one-man shows such as Circles and Dress to Kill at downtown venues like P.S. 122. His West End acting credits, however, are fairly numerous.

The original New York production of Joe Egg ran for 154 performances in 1968. Michael Blakemore directed Albert Finney and Zena Walker — who won a Tony Award for her portrayal. A 1985 revival starred Jim Dale and won a Tony Award for Stockard Channing. It ran for 93 performances.
