London's theatrical comedy epic returns - April 4-6 2025 at Pleasance London

More than 50 of the world's top comedy improvisers are getting together for a show that lasts an entire weekend. The sleep deprivation creates a hilarious euphoric show that is unlike anything else you will have seen. It's split into 25 2-hour episodes, each starting with a summary so you can drop in to any and know what is going on. For improv fans looking to pull an all-nighter, you can also get a Night Shift Pass to watch five episodes back to back from 11pm for £25 - just £5 per episode...
