Celia Harrison is a character from All the Old Knives, an American thriller film directed by Janus Metz Pedersen and screenplay by Olen Steinhauer. It is based on the novel of the same name by Steinhauer. The character is portrayed Thandiwe Newton.
Celia is a spy and Henry's ex-lover.
The story is set in the town of Carmel-by-the-Sea and follows ex-lovers — one a CIA spy, one an ex-spy — meet over dinner to reminisce on their time together at Vienna station. The conversation moves inevitably to the disastrous hijacking of Royal Jordanian Flight 127, which ended in the deaths of all on board. That failure haunts the CIA to this day, and Henry has come to Carmel to close the book on that seedy chapter. As they parry, flirting, over California cuisine, it becomes clear that one of them is not going to survive the meal.
