REVIEW: Bristol Old Vic in Wonder Boy, York Theatre Royal, 7.30pm tonight and 2.30pm tomorrow ****

Wonder-ful: Hilson Agbangbe’s Sonny in Wonder Boy. Picture: Steve Tanner

WHAT was the last play to capture the forlorn yet defiantly hopeful schoolroom experience so expressively? Willy Russell’s musical Our Day Out, with its busload of bored teens, springs to mind; John Godber’s Teechers even more so, especially in its Leavers 22 revamp.

In a new class of its own is Ross Willis’s Wonder Boy, an exploration of the power of communication with the aid of creative captioning, wherein the electronic screen captures every last repeated letter of young Sonny’s “Stammer Horror” experience.

At the helm of Bristol Old Vic’s touring production is Sally Cookson, whose unforgettable National Theatre staging of Charlotte Bronte’s Jane Eyre lit up the Grand Opera House with such vitality, imagination and innovation in 2017 that it won that year’s Hutch Award for Stage Production of the Year in York.

What her reading of Wonder Boy shares with her Jane Eyre is its focus on a central character’s struggles in a world seemingly set against them, taking up residence inside the head of the outsider so completely that we feel we are in there too.

In this case, 12-year-old Sonny (Hilson Agbangbe) lives with a stammer that leaves him silent and sullen at school. Words, not ideas, hopes or flights of fancy, evade him except when in the company of his imaginary friend, the combative word warrior Captain Chatter (Ciaran O’Breen).

The omnipresent caption and video design, courtesy of Limbic Cinema’s Tom Newell, charts every uttering of Sonny, whether fluent when kept inside that troubled head or when in conversation with rebellious, trouble-magnet friend Roshi (Naia Elliott-Spence), report-obsessed new head teacher Miss Fish (Meg Matthews at Wednesday’s matinee/Jessica Murrain) or his Mum (Matthews/Murrain again) in flashback scenes that trace her downward spiral.

Sonny expresses himself in his comic-book drawings, but inevitably bullying will spoil that well of creativity and expression in this struggling, downtrodden secondary school.

When the insensitive Miss Fish decides to impose the role of the Guard in Hamlet on him in the school play, Sonny finds an ally in the shape of unconventional deputy head Wainwright (Eva Scott), Wonder Boy’s answer to Godber’s new drama teacher in Teechers, Geoff Nixon.

Wainwright likes Ryvita nibbles, paper planes and Star Wars models; Wainwright dislikes Miss Fish’s methods, manner and form-filling excesses. For all her love of teaching, she will be the next to join the stampede of exits stage left from the teaching profession.

Willis writes with an anger and vigour, a frustration too, to match former teacher Godber – and that of Sonny too, although the boy’s determination to deliver his lines brings tears to the eye.

Cookson’s witty and wise direction combines with Willis’s astute writing to bring out the playful, scabrous humour as much as the pathos in Wonder Boy, not least in not shying away from the frank, “very sweary” language that adds even more impact.

Agbangbe and Scott, in particular, are terrific, their scenes together being the most moving your reviewer has seen on a York stage this year. Top marks too for Katie Sykes’s set and costume design, Laila Diallo’s Kapow-style movement direction and Benji Bower’s incidental compositions.

Wonder Boy is wondrous theatre, a lesson to us all in the importance of listening and breaking down barriers. Box office: 01904 623568 or yorktheatreroyal.co.uk.
