Book The Smartest Giant in Town at St Martins Theatre for Christmas 2026. Julia Donaldson musical with puppets and songs for ages 2 to 8, 9 December 2026 to 3 January 2027.
The Smartest Giant in Town is the Olivier Award nominated musical adaptation of Julia Donaldson and Axel Scheffler's picture book, returning to the West End at St Martin's Theatre from 9 December 2026 to 3 January 2027. George wishes he was not the scruffiest giant in town. After a trip to a fancy clothes shop he has a spectacular new look: smart trousers, a smart shirt, a stripy tie and shiny shoes. Then he meets animals who need his help, and his clothes. Choose your date and official seats on the The Smartest Giant in Town tickets page.
Little Angel Theatre and West End producers Fierylight bring the story to the stage with puppets, songs and a warm Christmas season run that shares West Street with The Mousetrap. Casting can change, so confirm details when you book.
Plan for 55 minutes with no interval, a length built for younger attention spans. The St Martin's Theatre sits on West Street in Covent Garden, a short walk from Leicester Square and Covent Garden Tube, with plenty of family friendly food nearby. Arrive early so children can settle before curtain. Daytime performances are the usual pattern through the holidays; check the listing for the exact start time on your date.
Pick a performance, compare seats for St Martin's, then book through The Smartest Giant in Town on British Theatre. Closer stalls seats help younger children see faces and puppets. Upper levels can still work if you want a full view of the stage picture. Confirm age guidance and any babe-in-arms rules for your party before you finalise.
There is no formal dress code. Comfortable clothes and shoes are fine for a family matinee. Leave time for West End pavements and the St Martin's foyers, especially in December. Outside food and drink are not allowed in the auditorium. Phones off, and no photography during the show. Pushchair parking is typically available at the venue; ask front of house on arrival.
For another Donaldson and Scheffler family show, see Room on the Broom. Older children ready for a longer musical often love Matilda the Musical.
Aimed at children aged 2 to 8. Babes in arms under 12 months sitting on an adult's lap typically do not need a ticket; everyone else does. Confirm the listing for your date.
