During the commentary she did for the DVD of Sunday Showcase: What Makes Sammy Run?: Part 1 (1959) Dina Merrill said that the treatment she received from director John Frankenheimer on this picture nearly drove her out of the business. He literally told her at the end of a days' filming that she was the worst actress he'd ever worked with. She said she went home in tears. It got so bad that her co-star Burt Lancaster came to her defense one morning by ridiculing the directors' "good mood" as evidenced by the fact that he hadn't insulted Dina yet.
When Burt Lancaster walked onto the set the first day of shooting, he was startled and dismayed to see the camera on the floor, aiming upward. Lancaster had never before worked with a director who used such innovative camera angles. He grew to trust John Frankenheimer, and they made four more films together.
