Their story

The IMPROZAC adventure began in September 2016, one year after the creation of Act’in Theatre.

When we are improvisers, we have no text, no character, no props… nothing on stage! Except… a team! That’s why it seemed obvious to us to create our troupe as soon as we started the workshop!

Why the name "IMPROZAC"?

One summer day, on our beautiful terrace in London, after a workshop, we were sharing a drink… or two, in short, it remains a detail!
We were looking for a name that would reflect our joie de vivre and our good mood!

After a thousand and one proposals, Improzac became an obvious choice. With the slogan: “If you’re depressed, take one prozac = IMPROZAC”.

This name is like a remedy for routine, for the worries of everyday life!
With IMPROZAC, enter a world of tolerance and benevolence, but above all a world that is surprising, innovative and full of surprises! A real breath of fresh air!

When to see the troupe?

To make it easier to meet up, we have created the Entre Act’ format which takes place every 5/6 weeks in London in an intimate venue.

Entre Act’ is a special two act format.
First act is a small theatre show. The troupe Les Gueules de Bois selects playlets from theatre or film which they assemble and perform in a light-hearted way in an intimate and minimalist setting.

Second act is an improvisation cabaret with the troupe Les Improzac! What could be more fun than improvising, sharing and above all surprising yourself!

So don’t hesitate to follow our calendar of SHOWS.
