Chatroom

Chatroom is a 2010 British psychological thriller drama film about five teenagers who meet on an online chatroom and encourage each other's bad behaviour. The story follows William (Aaron Taylor-Johnson), a depressed teenage boy who manipulates others online, including Jim (Matthew Beard) who suffers from depression, Eva (Imogen Poots) who is bullied at work, Emily (Hannah Murray) who feels distant from her parents, and Mo (Tuppence Middleton) who believes himself to be a pedophile. The group's dark dynamics culminate in William's descent into madness and the teens' desperate attempts to stop him.
