In this 'Unlock Art' documentary video from The Tate museum, Tamsin Greig gets to grips with humour in art.

In Unlock Art: What's So Funny?, Green Wing and Episodes star Tamsin Greig investigates how humour became central to many of the art movements of the past 100 years. The film examines how artists including Duchamp, Magritte and Gilbert & George employed humour in their work to ridicule the status quo and explores how humour was used to observe the role of the individual in relation to authority and politics.
