Born in Stockholm to a German mother and a Russo-Finnish father, Corduner grew up in a secular Jewish home in London.

[citation needed] Interest in arts and music was always encouraged at home, and Corduner's early ambition was to become either an orchestra conductor or a concert pianist.

TV appearances include Exile, ITV's Midsomer Murders, Stephen Poliakoff's Dancing on the Edge, and as Andrea Verrocchio in seasons 1 and 2 of the Starz original series Da Vinci's Demons.

After drama school, Corduner's first two years as a professional actor were spent playing a wide variety of parts at Newcastle Repertory Theatre.

Spells at the Birmingham Rep and the Actors' Company followed, until Corduner returned to London to make his West End debut in Mary O'Malley's Once a Catholic at the Wyndham's Theatre.

Corduner has appeared several times at the Royal Court Theatre, in plays such as Three Birds Alighting on a Field, Fucking Games, Ice Cream, and most notably Caryl Churchill's satirical Serious Money, which subsequently transferred to London's West End and Broadway in New York City.

Corduner's voice is familiar to listeners of BBC radio plays such as Insignificance, The Resistible Rise of Arturo Ui and Fanny and Alexander.

[7] Corduner and his partner Juha Leppäjärvi met in 2006 in London, forming their civil partnership in December 2009 and marrying in New York City in August 2013.
