Netflix drama Adolescence – a four episode mini-series where each episode was filmed in one shot – is provoking some emotional reactions online.

In the clip above Owen Cooper and Erin Doherty, the two main actors from episode 3 – which takes places almost entirely in one room – watch back their performances and give an inside into what was going on behind-the-scenes and in their heads while the camera was rolling.

Cooper probably sums it up best after one pivotal moment: “That was tense.”

Adolescence is streaming now on Netflix.
