Wrecks by Neil LaBute

Edward Carr is played by Robert Glenister in a one man show directed by Josie Rourke and designed (for our extreme comfort) by Lucy Osborne.

Seen at The Bush Theatre in a room that resembled a funeral home from top to toe

A tour de force is the obvious comment here. Robert was devilishly charming while we all patiently waited for Mr LaBute to drop his twisted bomb - and he didn't disappoint. A glorious performance of a delicious drama.

Edward Carr is an ordinary man; a doting father of four and a successful businessman. His world has been shattered by the death of his beloved wife JoJo. Through his grief, he picks through his past, piecing together the story of his life, like the wrecks of the cars he so lovingly restores.
A fiercely passionate and unflinching monologue about the nature of life and death, and what society will accept in the name of love.
Neil LaBute's previous plays include The War on Terror, Helter Skelter/Land of the Dead, The Shape of Things, The Mercy Seat, Fat Pig and In a Dark Dark House.
Robert Glenister is known to millions for his performance as Ash Morgan in the hit BBC drama Hustle and as the Home Secretary in Spooks. His extensive theatrical career includes regular performances for the RSC, National Theatre, Royal Court and West End.
