Actorworks
Actorworks claims to be the UK's only drama school where the training is specifically based on the teaching of American theatre practitioner, Viola Spolin.
The school is situated in Raine House in Wapping, London and is run by its founder, Daniel John Brennan. There are three main courses: a one-year full time intensive course and a one-year part time course (both of which run in the evenings and weekends); and a foundation course which runs for 15 weeks during the day, from November to April.
