All Creatures Great and Small star Nicholas Ralph has joined the star-studded cast attached to Wax Fruit, an upcoming series based on Scottish author Guy McCrone's internationally best-selling trilogy.

The drama, which is currently in development by Glasgow-born showrunner and executive producer Sarah Purser, follows the rise of the Moorhouse family from humble beginnings in rural poverty to the heights of 19th-century Glasgow society. Intrigued? Here's all we know so far. 

What is Wax Fruit about? 

The upcoming series blends "sweeping, character-driven period drama with a sharp, modern edge" and is described as "Succession meets Bridgerton, in tartan", according to the synopsis.

It reads: "Set between the Gaelic-speaking Highlands and the gritty streets of Victorian Glasgow, Wax Fruit follows the explosive rise of the Moorhouse family, who leave rural poverty behind to climb into the ranks of the city’s powerful merchant elite — at a time when Glasgow was one of the most glamorous and powerful cities in the world."

Emun Elliott (The Gold) has also joined the cast. 

On signing on to the adaptation, Nicholas said: "Sarah's passion, energy and deep knowledge of the material and history was totally inspiring and with the incredible Scottish actors and creatives she had involved - some legends - I was already enamoured."

He continued: "Then Sarah sent episode one. I devoured it - all the characters are so well drawn and unique but at the heart you have the big bold Moorhouse family. I love the world, the time period and these wonderful characters and I am so invested. Needless to say, I’m very excited to be joining the Wax Fruit gang."
