Keeley Hawes will appear in BBC1’s adaptation of JK Rowling‘s global best-selling novel The Casual Vacancy.

The actress, who recently won acclaim for her role in BBC crime thriller Line of Duty, will play troubled mother Samantha Millison in the three-part series, which will follow the tensions and rivalries in the quiet fictional town of Pagford following the sudden death of a local councillor.

The Casual Vacancy, which begins filming in the West County next month, has been adapted by writer Sarah Phelps, whose recent credits include The Crimson Field, and will also star Michael Gambon as Samantha’s deli-owning father-in-law, Julia McKenzie as his wife, W1A’s Rufus Jones as Samantha’s husband and Rory Kinnear as the ill-fated councillor.
