Amber Heard has been cast alongside Kevin Costner & Liam Hemsworth in the McG's upcoming action thriller Three Days to Kill. The movie follows a Secret Service agent played by Costner "who decides to retire in order to reconnect with his estranged family. Heard plays the woman who offers him access to an experimental drug that could save his life in exchange for one last assignment, which Costner must complete while coping with the drug's hallucinatory side effects." Luc Besson penned the script alongside Adi Hasak. Heard will soon be seen in an indie film called Syrup with Shiloh Fernandez, Kellan Lutz & Brittany Snow.
