Sienna Miller Reveals Daughter Marlowe Was Going to Be an Extra in 'Horizon: An American Saga' (Exclusive)

Chapter one of 'Horizon: An American Saga' hits theaters on June 28.

I have this photograph of Marlowe and Kevin around the monitor and he's got one headphone in his ear and he gave her the other, he's got his arm 'round her and I have a picture from the back and it was so special. Kevin really held him to task, he didn't give him special treatment, he was hard on him and I think Hayes loved it. ET spoke with Costner in April about co-starring with his son and how watching Hayes grow up served as a constant reminder that he had to get moving on Horizon: An American Saga.
