How do you watch a play in the dark?

A play that takes place in total darkness premieres in the UK this week.

The audience enters in the dark. The actors are never seen. The ushers wear night vision goggles.

Tutto Bene, Mamma? - a one-act drama adapted by April de Angelis - tells the true story of a mother and her young boy in an apartment in the Italian city of Naples.

Actress Laura Donnelly and stage manager Kay Hudson explain what it is like putting on a play in the dark.
