Animal Action

In the scene where the actress walks into a bedroom and sees an old woman holding her baby with a lamb standing next to her, production wanted a lamb to stand on a large platform covered with cloths next to the actress. Prior to shooting, the handlers brought both lambs to set. One of the lambs was merely a backup and they placed the lamb on the platform.
When everyone in place, the handler placed a lamb on her mark and stayed until she was comfortable. Handler was off-camera the whole time. They filmed the lamb standing on the platform.
