If you want to see the hit musical “Matilda” before the Civic Theatre stages it next year, you have just three chances this weekend.

McDuffee Music Studio bursts onto the theatrical scene with its ambitious all-youth production. Note this London and Broadway hit is by two of the most devious minds to write material safe for children: the late author Roald Dahl and comic songwriter Tim Minchin. While the story is dark at times, the sheer absurdity of all the characters and situations keeps it light.

In this musical, with book by Dennis Kelly, the Wormwoods – a Latin dance-obsessed wife and proudly unethical used-car dealer husband – prefer their children to be like their son, Michael, comically ignorant and male. Surprise-baby Matilda is definitely neither. She insists on reading books, visiting the library and telling stories. And when she’s had enough mistreatment, she tends to be “a little bit naughty.” Perhaps some abuse at the local school, led by wicked Mrs. Trunchbull, will cure her of that.

Having an all-student cast is easy for this show, as most of the roles are children, but some local teens ably step up to fill the “adult” shoes.

William Baartz as the viciously imposing Trunchbull manages to fully embrace the extreme silliness of the role. The teen-boy musculature stuffed into an Olympic women’s hammer-thrower form only adds to the look – equal parts threatening and cartoonish.

On the other end of the scale, Kamdyn Knotts is so very charming as teacher Miss Honey, a mousey woman struggling to find her voice to help Matilda. Her willingness to show weakness and work to overcome it ironically makes her the most (if not only) mature character in the show. Krissy Brzycki as librarian Mrs. Phelps is another ray of sunshine in Matilda’s life, practically starving for the girl’s story that may or may not be fiction.

Josh Hoover impressively shows range in dual roles as a vapid dance partner and an “escapologist” in love.

Ayden Cress and Kennedi Bruner are both a hoot as Mr. and Mrs. Wormwood, despite their neglectful and somewhat abusive nature. Wesley Olin as Michael shows that rare natural talent at playing an imbecile so entertainingly he can’t help but steal the scene, even just shouting one word.

As for Kate Honaker as Matilda, to us she looks and sounds straight off the Cast Album. Honaker holds focus and makes us believe in this girl with so many brains (yet they “just fit”) and a little bit “extra” that her stressful journey brings out.

The other children are more than just chorus to Matilda’s story, as they learn to deal with a cruel yet silly world. Colton Woods as Bruce Bogtrotter gets to revel in being an unlikely hero. Brilynn Knauss as Nicole gets a quick lesson on improvising one’s way out of trouble. And Izzy Napier’s hyper Lavender declares herself Matilda’s “best friend,” then takes on one of the more notorious pranks on the Headmistress.

We would like to assure you that no newts were harmed in the making of this show, but you can buy (a rubber) one at the concession stand, as well as chocolate cake.

While the production does have its technical flaws, it is energetic and earnest. Remember that one of the main tenets of the story (like most of Dahl’s work) is that not all stories have a happy ending. But it does manage to keep a positive outlook even at the grimmest point.

If you have any children in your care this weekend, especially those of grade-school age, they will be practically falling out of their seat with laughter and delight at the show. Performances of “Matilda: The Musical” are 2 and 7 p.m. Today, 2 p.m. Sunday (May 25-26) at Lutheran High School, 5555 S. Arlington, Indianapolis. Tickets are $10, $12 for premium seats.
