The Ferryman produced at the Royal Court in association with Sonia Friedman and Neal Street Productions was the Royal courts fastest selling production. It opened on 24th April 2017 and ran for one month, transferring to the Gielgud Theatre in June. Rachel assisted Peter Mumford keeping paperwork and plans up to date as well as translating the plan into the new space and making sure the focus plot was up to date for the run and any future productions. In October Rachel went in to the theatre to make updates due to the cast change. The Ferryman was extended for a second time running until May 2018.

In this article Peter talks about the production and his creative process:

Shortly after the end of the run it was announced that the Ferryman would be transferring to Broadway.
