Ioan Gruffudd as Andrew Earlham in Liar

Gruffudd (whose full name is pronounced ‘Yo-Ann Griffith’) was born and raised in Wales where he started his acting career at the age of 14 on a Welsh-language soap opera called Pobol y Cwm (People of the Valley).

Go back and re-watch Titanic because, before he was famous, Gruffudd appeared in the 1997 blockbuster as Fifth Officer Harold Lowe. Lowe was the only officer on board the Titanic who went back to save any survivors of the wreck.

You might have missed him the first time because it wasn’t until a year later that he landed his first major role in Britain, playing the fictional Napoleonic war hero Horatio Hornblower.

Gruffudd appeared in a series of TV films about the Royal Navy officer between 1998 and 2003. After five years as Hornblower, Gruffudd became a household name in the UK and a bit of a heart-throb too.

Andrew Earlham is a charming and well-respected surgeon

From there, Gruffudd and his wife, fellow actor Alice Evans, moved to the US where he played Mister Fantastic in Fantastic Four and starred in the TV shows RingerForever and UnReal.

Gruffudd returned home to the UK to film Liar, which he has described as “controversial yet relevant”.

He plays Andrew Earlham, a charming and well-respected surgeon who is accused of rape after going on a date with teacher Laura Nielson.

But his story of the night is very different from hers. Who is lying?
