Laboratorio Teatro Settimo isn't just a gorgeous name for a theatre company; the Turin group also produces beautiful theatre, to judge by this achingly inventive evocation of life under the sea. Unfortunately, being performed almost entirely in Italian, Aquarium at the Ark is a bit of a fish out of water.

Aquarium is really a theatrically illustrated children's book about marine ecology, but when the children can't follow the text they are missing something of the play's content and its intent. The imbalance isn't fatal - the cast makes a remarkable connection with the eight- to 12-yearolds - but it's an imbalance nevertheless.

It succeeds as far as it does because of the amazing things Andrea Violato can mould with his face, Mimma Pieri can achieve with a gesture and, most beautifully of all, Roberta Biagiarelli can do with her eyes. The three achieve that Italian combination of pure grace and hysterical clowning. Atmospheric music and a lot of ultraviolet light help the child's play too.
