Previously titled "Three Days To Kill", Luc Besson and Adi Hasak penned the script in which Costner stars as a Service agent who discovers he’s dying. Before he goes, he attempts to complete a final mission, and reconnect with his estranged daughter (Steinfeld).
He’s also taking an experimental drug that could prolong his life, but causes hallucinatory side effects. Heard will play Costner's handler, while Nielsen will play his ex-wife.
Besson, Hasak, Ryan Kavanaugh and Virginie Besson-Silla are producing. The film is currently in production in Paris ahead of a further filming in Serbia.
