In a press statement, Powell commented, "I'm delighted to be back in the West End and joining this classic musical. On the night I went to see it, from the minute the curtain went up I knew it was a show for me and I'm thrilled to be working with such a talented company. I've also dealt with a few studio bosses in my time so inspiration for the part of RF Simpson should come pretty easily! I can't wait to get started."
