Joanne let her dress take centre stage as she kept the rest of her look simple, accessorising with circular stud earrings and a dainty ring. She wore her blonde hair pulled back into a low chignon and kept her makeup fresh and minimal.
The actress was joined by her Last Light co-star Matthew, who looked dapper in a black suit, white shirt, and a beige tie.

The five-episode drama is based on Alex Scarrow's bestselling apocalyptic thriller novel, Last Light, which tells the story of a family fighting to survive in a world that has been suddenly thrown into chaos.
Joanne plays Elena Neilson, a smart and caring mother who gave up her thriving career to focus on finding a cure for her son, Sam, who has a progressive, degenerative eye disease, reports Deadline.
Elena "has become a leading fundraiser for a foundation pursuing cutting-edge research into Sam’s condition. This maternal and professional triumph for Elena is only tempered by the state of her marriage, which has been strained to the breaking point".

Meanwhile, the TV festival also saw appearances from Princess Charlene and Prince Albert of Monaco and David Hasselhoff and his wife Hayley Roberts.
