Broadway actress Kristen Beth Williams is to join the cast of Top Hat from February, playing Dale Tremont.
Williams, who has appeared in Nice Work If You Can Get It and Anything Goes on Broadway, takes over from Charlotte Gooch, who joined the cast in November last year. Gooch replaced Summer Strallen in the production, which is running at the Aldwych Theatre in the West End.
Also joining the cast in February will be Alex Gaumond, whose West End credits We Will Rock You and Legally Blonde the Musical.
Both Gaumond and Williams join the previously announced Gavin Lee, who will play the part of Jerry Travers in the musical, which is directed by Matthew White.
Clive Hayward, who was recently in Yes Prime Minister at the Trafalgar Studios, also joins the company from next month.
Top Hat, which has music by Irving Berlin and is based on the Fred Astaire and Ginger Rogers film of the same name, is booking until April, 2014.
It has choreography by Bill Deamer and is produced by Kenny Wax, with Stewart Lane, Bonnie Comley, Ted Hartley, Flora Suk-Hwa Yoon and Lee Menzies.
