Director Véra Belmont recalled that Charlotte Valandrey, who was 16 during filming, was "nice but a bit annoying' and that he was dreading about her love scene (where Charlotte appears topless). " The little girl was new to the subject and I didn't want to shock her. Lambert (Wilson) had the brilliant idea of playing with Charlotte as if she were a little cat. He played down the situation and was able to stroke her gently without hurting her feelings. It went like clockwork," Belmont said.
