Krumholtz had left the cast of the Ahmanson Theater play due to personal reasons.
In just a few weeks, "The Hangover" star has to perfect the role of agent Ben before the production opens for previews Sep 24, reports femalefirst.co.uk.
The play's cast has been shuffled in the past too. Actor Richard Griffiths was set to reunite with actor Danny DeVito here after working with him on the West End stage in London, but Griffiths died in March 2013.
He was replaced by Judd Hirsch.
