Sea Sick

The Theatre Centre production

written and performed by Alanna Mitchell

22 Apr to 7 May
Running Time: tbc

Sea Sick

The ocean contains the switch of life. Not land, not the atmosphere. The ocean. And that switch can be turned off.

Following a sold-out run at the Edinburgh Festival and a Canadian tour, the Theatre Centre’s critically acclaimed production about the state of the global ocean, written and performed by Alanna Mitchell, comes to the National Theatre.

In this powerful story, Mitchell uses science and wit to tell us about her journey to the bottom of the ocean, the demons she discovered there, and her hope for the future.

‘Terrifying, laugh-out-loud funny, and ultimately hopeful. A must-see.’
Vancouver Observer
