50-Hour Improvathon - Pleasance Theatre

A 50-hour-long marathon of improvisation. Yes, you read that correctly: 50 hours. As this reviewer writes, people still have another 24 hours of complete and utter madness to sit through. The Pleasance puts on this event every year, and for regulars it seems to be an absolute highlight. This year, we find ourselves in Pleasanceville in the year 1980… something — a sort of makeshift parody of the Stranger Things universe.

The event works in a very clever way: every odd hour (1pm, 3pm, etc.), a new episode begins. Each episode runs for 1 hour 40 minutes, with a 20-minute break before the next. It’s incredibly welcoming to newcomers because, at the start of every episode, we’re given a short introduction to the characters, as the actors rotate to get some rest. Although we don’t get a full recap of what’s happened previously, that’s not really necessary to have a great time — most of the fun lies in the improvisation rather than the plot itself.

There are very few shows where the line between audience and performers becomes this blurred. Here, as the audience grows more and more exhausted over time, it manifests in uncontrollable yawns or sudden, manic bursts of laughter. Somehow, this only seems to make the cast more chaotic, turning the challenge into even more fun for everyone involved. When this reviewer joined, the event was already in full swing at its 18th hour. The first episode I saw was a new addition this year — a Dungeons & Dragons special led by D&D master Mark Meer. Although I’ve never played D&D, my limited knowledge from The Big Bang Theory was enough to catch the gist. That said, it was entirely possible to enjoy the madness without any prior experience of the game.

Each episode is directed on the spot, with most scenes beginning with a short task for the actors to complete. That can be anything from “I want X to apologise to Y and see where it goes” to “Each of you must now adopt a different accent. If you invent a new one, you’re kicked off the stage.” The cast take these prompts and run with them, creating some of the most chaotic and inventive scenes of the night. Featuring performers from the Olivier Award-winning Showstopper! The Improvised Musical and the Tony Award-winning Mischief, alongside comedians, up-and-comers, and international guests throughout the weekend, the sheer level of talent on that stage is undeniable. It takes real skill to make any sense out of that much chaos — especially when it’s all happening in the moment.

The only real downside to the experience is the physical discomfort that comes with sitting for such long stretches. As someone with back pain, I struggled to find a position that allowed me to sit without it becoming a distraction, and the wooden chairs aren’t the most forgiving for hours on end. This won’t come as a surprise, but it’s worth noting. That said, the breaks are there for a reason — use them to stand up and walk around.

Whilst I only attended 3 episodes today (still adding up to 6 hours worth of theatre), I genuinely understood the entire appeal of the experience. At the risk of sounding redundant, accepting the chaos of the performers and letting random storylines emerge from nothing is the best way to enjoy this atypical production. There aren’t many artists that would dare to lay themselves bare on the stage by acting the real fool, in the best way possible. It’s a real commendable achievement, and an honour to watch.

This is not an event designed for comfort, casual viewing, or even total narrative coherence. It is a test of stamina — for the performers as much as for the audience — and that is precisely where its appeal lies. The occasional physical strain and the deliberately loose storytelling are not flaws so much as the price of admission for something genuinely unrepeatable. In an art form that often talks about “being in the moment,” this production takes that idea to its most extreme and joyfully chaotic conclusion.
