Casting News: John Hollingworth, Harriet Ballard, Gracee O'Brien

Hot on the heels of last week's casting announcements for Poldark we have a few announcements of our own that we've gathered from Twitter.

John Hollingworth joins the cast as Captain Henshawe who helps Ross with the mines. John is currently appearing in An Intervention at Watford Palace Theatre. You can catch him there until 3 May .

Young Cornish actor Gracee O'Brien has been cast as  Jinny Martin. Gracee is with the Cornwall Youth Theatre and has just finished appearing in Before I Wake at Heligan Gardens.

We're waiting to hear what role Harriet Ballard has been cast in but we know she had a costume fitting a couple of weeks ago when she tweeted, "Big Thank-you 2 the lovely costume ladies Marianne, Hava & Jan for corset& costume madness yesterday @BBCOne @mammothscreen #Poldark"

Harriet has appeared in Lewis and Switch. (As a little bit of trivia, she starred alongside Lacey Turner in Switch and Lacey has appeared in Being Human with Aidan Turner).
