The play opened March 24 following previews that began Feb. 28. The limited engagement was originally scheduled to run through July 5.
The play is billed as being about an international photojournalist and a New York gallery owner "who discover each other and also that there might be an art to repairing broken lives."
The production marks Allen's first return to Broadway since The Heidi Chronicles in 1989, and Irons' first time on Broadway since The Real Thing in 1984.
