Eva Marie Saint told About.com that she and Brandon Routh did a complete scene before finding out none of it was filmed:
"I was in the very beginning of that when they first started shooting. What is the name of that new camera? Genesis. It's not film. It was the very beginning of the movie and Brandon Routh [and I] had this emotional scene. He has to come home after five years. He's been gone and we played this emotional scene, the first time that we were really working together. We went on for about an hour and then the cinematographer said, 'I'm sorry, I didn't get it.' It's not like you check to see the film. Somebody just wasn't doing their job."
She talks more about the scene and gives a spoiler on another scene at the link above.
