From Scenes Into Shows

Saturday 11 & Sunday 12 June, 10am – 4pm £80


The perfect course for improvisers who are confident performing individual scenes and wish to craft these together into funny, high quality shows. 

This four part course focuses on bringing isolated scene work skills together to create comprehensive pieces of improv comedy. You will learn the language and style of different longform improv scenes, plus the skills required to unite them, such as editing, reincorporation and game. Discover how a strongly grounded base reality is the platform you need to allow your improv comedy to take off, plus how to take characters beyond silly voices and goofy walks and into grounded 3-Dimensional people you can build entire worlds around. 

Ideal for recently formed teams, or those looking to run their own shows, or individuals who want to move forward to the next stage of their improv career. 

Saturday 11 & Sunday 12 June, 10am – 4pm £80

She plays on the superb weekend team Grandma’s Ashes, a delightful team that play with so much joy, support and energy that their comedy feels almost communal.

Zeke Nicholson is a performer/writer hailing from Rhinebeck, New York and performs for UCB LA house team Cardinal Redbird.

Improv: Controlled Chaos with Zeke Nicholson

Wednesday 11th 7pm-10pm £20 Buy Tickets
Many improv scenes and sets can be “technically correct” yet still somehow suffer from not being dynamic enough. This workshop will focus on methods to introduce a little bit of chaos into your scene work, making unexpected and bold choices that keep the improviser ahead of the audience, and fostering a greater sense of play. It’s important to be able to stay on the rails, but it’s also important to jump out of the cart and fall down the mountain every now and again.

Sketch Heightening with Zeke Nicholson

Thursday 12th 7pm-10pm £20 Buy Tickets

Take your scene further by heightening and exploring its game faster. We will discuss some examples of sketches that heighten well, and talk about how to quickly establish and explore a game. Students will bring in a sketch of their own that could benefit from some heightening, then the class will act as a writers room to come up with ways to blow out the game as much as possible.

Comedic Storytelling with Zeke Nicholson

Saturday 14th 11am-2pm £20 Buy Tickets

This workshop is geared toward deriving humorous, relatable, true-to-life material to begin crafting a usable storytelling piece. The class will do exercises to unearth interesting nuggets from our lives, and then help identify which of our experiences might be fruitful source material for further polishing. Whether you have an interest in creating an autobiographical one-person show, are an improviser looking to flex a different muscle, or just a fan of The Moth podcast, this will be fun and not scary I promise!

Character Development with Lydia Hensler

Mon Jan 30th, 7-10 pm £30 Buy Tickets!
Have you written or performed a solo character piece? Do you have a note in your phone with funny character ideas? Did your uncle do something weird at a family function and you were like “Is this something?” This workshop will focus on the process of taking your ideas to the next level. Students are encouraged to bring original material or at the very least ideas and pitches they have thought about. Together we will cultivate ways to grow your ideas. It doesn’t matter where you are in the process, this class will get you where your at and hopefully inspire you to where you’re going next.

Joyful Game with Lydia Hensler

Tuesday Jan 31st, 7-10 pm £30 Buy Tickets!
If you’re not having fun, neither is the audience! This class will focus on letting joy be your guide in developing game based scenes.

Keep Making Choices with Lydia Hensler

Wednesday Feb 1st, 7-10 pm £30 Buy Tickets!
This class will not only be about making bold fun choices, it will be about sustaining them throughout the scene. This is good for anyone who feels like they get stuck after a couple minutes into a scene, or for anyone who’s ever silently begged for an edit in their head. Learn to play in a way where you feel fearless and never want to leave the magic you’ve created.


Two Up
