Una Merkel recalled filming the fight sequence: "Neither of us knew what we were doing. We just plunged in and punched and slapped and kicked for all we were worth. They never did call in the stunt girls. Marlene stepped on my feet with her French heels. The toenails never grew back. She was stronger than me. She was very powerful and I was very thin. Luckily, I have a remarkable constitution. I was bruised from head to foot when it was over. I looked like an old peach, green with brown spots. And I felt like one too. At the end of the scene Jimmy Stewart came in and dumped a whole bucket of water over us. He did it in long shot. Then he had to do it over for close-ups. Then Life Magazine wanted pictures so they did it over again. He dumped water on us for hours."
