Thesp Hannah Waddingham, who has played the Lady of the Lake in “Monty Python’s Spamalot” in London and on Broadway, will play Desiree in Trevor Nunn’s upcoming Menier Chocolate Factory revival of “A Little Night Music.” The production plays Nov. 22-March 8 with a Dec. 3 opening.

Nunn’s casting of 34-year-old Waddingham denotes a reconception for the Stephen Sondheim/Hugh Wheeler tuner. Glynis Johns was 49 when she created the role on Broadway in 1973, while Judi Dench was 60 when she played it in London’s last revival at the National Theatre in 1995. The casting is closer to that in Ingmar Bergman’s film “Smiles of a Summer Night,” on which the tuner is based.

Waddingham is joined by Alexander Hanson (“Marguerite,” “The Sound of Music”) as Frederik, Jessie Buckley (BBC TV’s “Oliver!” reality casting show “I’d Do Anything”) as Anne and Maureen Lipman as Mme. Armfeldt.

Kelly Price is in negotiations to play the Countess; already confirmed are Alistair Robins as the Count, Gabriel Vick as Henrik, Kaisa Hammarlund as Petra, Grace Link as Fredrika and Andy Morton as Frid. The Liebeslieder singers will be played by John Addison, Laura Armstrong, Lyndon Edwards, Charlotte Page and Nicola Sloane.

Sets and costumes are by David Farley, who was Tony-nommed for his designs for the Menier Chocolate Factory’s last Sondheim revival, “Sunday in the Park With George,” which had a Broadway run last spring.
