Mammals is a play by Amelia Bullmore. It was first staged at the Bush Theatre, Shepherd's Bush, London, from 6 April to 7 May 2005. This production then toured the UK in Spring 2006. With a cast of six, including Niamh Cusack, Mark Bonnar and Nancy Carroll.
The playwright was awarded the Susan Smith Blackburn Prize for the work.
The play depicts a marriage in crisis following husband Kev's revelation to his wife Jane that he is in love with someone else. The arrival of Kev's best friend Phil with his whirlwind of a girlfriend triggers a series of confessions which threatens to upturn all of their lives. Kev and Jane's increasingly desperate attempts to discuss their problems whilst hiding them from their two daughters makes for an insightful and often painfully amusing drama.
