Early life and education

Leech was born in Killiney, County Dublin, Ireland, to David Leech, the CEO of a computer systems company, and Kay Leech, a housewife. He is the third of four children; he has an older brother Greg, an older sister Ali, and a younger brother Simon. He attended St Michael's College. He became interested in acting at 11 when he was given the part of the Cowardly Lion in a school production of The Wizard of Oz and found he loved being on stage. He recalled how he immediately decided to become an actor when Peter McDonald told him how acting is a profession on the last night of the production's run. Afterwards, drama became the "focal point" of his teenage years, apart from his family life, and drama and family support helped him through his school years. He became set on acting after winning a small role in a 1998 production of A Streetcar Named Desire at the Gate Theatre. He earned a Bachelor of Arts and a Master's Degree in Drama and Theatre Studies from Trinity College, Dublin, later noting that this was a "loophole" in his parents' stipulation that he earn a degree to fall back on if he failed to have success as an actor. He landed his first major roles in Cowboys & Angels and Man About Dog while at Trinity, and he has admitted that he did little schoolwork because he spent his time on auditions and acting.

Career

Leech's first professional stage role was at the Gate in their production of A Streetcar Named Desire. "I was the gentleman caller to Frances McDormand's Blanche Dubois. The Coen brothers were walking backstage, and me a naive 16-year-old."

He appeared as Willi in the Queen and Peacock, at the Garter Lane Arts Centre. The following years, Leech was in Tom Murphy's The Morning After Optimism and then Hugh Leonard's Da at the Abbey.

Leech's breakthrough film performance was in Cowboys and Angels, in which he played Vincent, a gay fashion student, followed by the 2004 cross country caper film Man About Dog, in which Leech plays Mo-Chara, one of three Belfast scallies who get in way above their heads.

Leech played the role of Shane Kirwan in the Ireland's RTÉ series Love Is the Drug, in which he received a Best Actor nomination from the Irish Film and Television Awards. He followed that up with the role of Willy in the television series Legend, which is the story of three different Irish families. He received a Best Supporting Actor nomination from Irish Film and Television Awards for his performance.

In 2007, Leech appeared in the HBO drama series Rome as Marcus Agrippa, Octavian's top soldier and friend.

The film, Rewind, opened in Ireland on 25 March 2011.

In 2010, he appeared on the small screen in The Tudors as the doomed Francis Dereham, former lover of Catherine Howard. Leech also appears in ITV 2010s television series Downton Abbey as chauffeur Tom Branson, whose political ideologies clash with the upper class. He plays the role of officer Sam Leonard in television series Primeval in 2011 in series five. Leech also stars in the 2012 film adaptation The Sweeney.

Leech was voted sexiest Irish male in 2005 in U Magazine. He was named one of GQ's 50 best dressed men in Britain in 2015.

Personal life

Leech dated television presenter Charlie Webster in 2014-15.
