Casting is now complete for the largest-ever staging of Michael Abbensetts' Alterations, which will play London's National Theatre beginning February 20.

Directed by Lynette Linton, the era-defining comedy will be seen in the Lyttelton through April 5. Watch a trailer for the upcoming production in the video above.

The cast will be led by the previously reported Arinzé Kene (Get Up, Stand Up: The Bob Marley Story) as Walker Holt, Cherrelle Skeete (Hanna) as Darlene Holt, and Gershwyn Eustache Jnr as Buster. They will be joined by the newly announced Karl Collins (Nine Night) as Horace, Raphel Famotibe (Wonder Boy) as Courtney, and Colin Mace (War Horse) as Mr. Nat with ensemble members and understudies Tyler Fayose (Phoenix Rise), Richard Emerson Gould (The Vaudevillians), Joshua John (Romeo & Juliet), Samuel Nunes de Souza (The Prince and the Pauper), and Yolanda Ovide (Slave: A Question of Freedom).

Alterations illuminates the Guyanese experience of 1970s London, with additional material by Trish Cooke. The 1978 play follows Walker Holt, who has big dreams for his tailor’s shop and an even bigger order to complete. Over the course of 24 hours, he must work tirelessly to satisfy his new client’s impossible tailoring needs.
