This is what we found on Wikipedia regarding the Mischief Movie Night:

Mischief Theatre is a British theatre company that was founded in 2008 by a group of students from the London Academy of Music and Dramatic Art in West London, and directed by Henry Lewis, Jonathan Sayer, and Henry Shields. The group originally began by doing improvised comedy shows, but by 2012, they expanded into comedic theatrical performances that include choreographed routines, jokes, and stunts.

The company is primarily known for their comedic performances as the fictional theatre company, The Cornley Polytechnic Drama Society, enacting amateur performances that go wrong. Works by the company includes the award-winning 2012 stage play The Play That Goes Wrong and the BBC television series The Goes Wrong Show. Several of the stage performances by the company have been shown in the West End of London, and also in theaters throughout the United Kingdom and across North America and Europe.
