In more recent years, she has featured in a number of popular TV shows, including ITV drama Liar alongside Joanne Froggatt and Ioan Gruffudd.

In 2013, Zoë told The Telegraph she felt producers kept casting her as “wenches and harlots” in the early days of her career.
When you are fresh from drama school and eager to please, you will do those sorts of scenes just to appear obliging.
She told the newspaper: “That was my prostitute phase, and I was a bit more buxom back then. After I appeared in that, I kept getting cast as bawdy wenches and harlots, and being asked, persuaded, and in one instance bullied into doing nude scenes.
“Honestly, I can’t tell you the number of scripts I read where my character enters and, for some unfathomable reason, immediately removes her top.”
Zoë added: “When you are fresh from drama school and eager to please, you will do those sorts of scenes just to appear obliging, but I’ve learned that I’m actually a bit of a prude and now I put my foot down and am much more discerning.”

“When we got to the place in Wales and saw how amazing it was, it was on this gorgeous rock looking out to sea, they just thought, ‘Actually we can’t use horses, we have to use a boat’.”
