It begins performances at the Menier Chocolate Factory Sept. 20 prior to an official opening Oct. 1, for a run through Nov. 10. It is directed by Ian Talbot.

In the play, Charley's rich Aunt, Dona Lucia, is visiting from Brazil and the timing couldn't be better. Her presence as a chaperone will allow him and his friend Jack to ask their respective true loves, Amy and Kitty for their hands in marriage. But time is ticking, so where is Charley's Aunt? On learning she will be delayed by several days, they blackmail their eccentric friend Lord Fancourt Babberley (Horne), to save their romantic plans and pose as Dona Lucia. But then Charlie's real aunt arrives…

The role has previously been played by actors that include Richard Goolden, Leslie Philips, John Mills, Frankie Howerd, Tom Courtenay and Griff Rhys Jones.

Horne last appeared in the West End in Entertaining Mr. Sloane at Trafalgar Studios, opposite Imelda Staunton. Other TV credits include being a series regular in the "Catherine Tate Show" and appearances in "Worried About the Boy," "Roman's Empire," "Billy Goat's Gruff," "Teachers" and "20 Things to Do Before You’re 30."
