Heartstopper and Agatha All Along star Joe Locke makes his West End debut in the UK premiere of Clarkston by Samuel D. Hunter.

Jake (Joe Locke) arrives in a small town and starts working the night shift at Costco, stacking shelves. Partnered up with Chris (Ruaridh Mollica), the two youngsters form a friendship. Jake divulges he has Huntington’s disease, a degenerative neurological condition with an execution date. But before the disease takes his life, he wants to see the ocean and this is just a stopping off point along the way.
The unlikely pair come from different worlds and their friendship is volatile, fuelled by Chris’s mother Trish’s manipulating and cruel relationship with her son. They boys explore their sexuality, suicidal tendencies and troubled childhoods, culminating in a charming story of two youngsters, coming of age.
The three actors are all amazing. Ruaridh Mollica leaves his heart on the stage as Chris, hard on the outside but an emotional wreck on the inside and Joe Locke (whilst having the least meaty role in the play) does a fine job with the script. Sophie Melville may come in to the play a third of the way through but she certainly makes up for the loss of stage time, delivering a powerful portrayal of the mother who you can’t decide whether to like or hate.
The play is a bit all over the place, feeling like it was put together in a rush. The way it immediately jumps from the two boys meeting on their night shift to having sex down by the river (something which comes out of no where and there is no build up to – no flirtation or suggestion that the pair might be heading that way). Then there is Sophie Melville’s character of mother, Trish, who explodes on to the scene too late in the Play. The show should open with Chris leaving home because of his mothers addiction issues, introducing this part of the story from the outset and framing what is set to come.
The story meanders along for ninety minutes telling a story of friendship, acceptance, love and the hope of new discoveries. But whilst the idea is nice, it feels padded out with long readings from books and no great substance. Nice enough but in a city full of Plays right now, there are better ones out there to spend your money on.
