在新西兰的电影资料馆意外发现了失落已久的希区柯克早期作品，这或许是悬念大师本人会喜欢的桥段。
1923年的《白影》是“诡异、充满戏剧性的默片，它由Betty Compson饰演一对双胞胎姐妹，一位天使般纯洁，另一位‘没有灵魂’”。它包括“神秘的失踪、错误的身份、咸湿的歌舞、罗曼史、机缘巧遇、疯癫，甚至灵魂的轮回”。根据电影资料馆发布的资料，“批评家指责故事情节不合理，但对表演和‘聪明的制作’表达了赞许。”

A young Englishman abroad, Michael, visits the local low-life spot of Tiger Bay to test his assertion that the spirit of human romance survives even in the most unpromising of circumstances. He intervenes when a local criminal protection racketeer targets a Chinese nightclub, and falls in love with the owner's young English foster-sister. But Olaf's gang have only just started their campaign against Lui Chang, the cultured, elegant woman who owns the premises... and she is determined not to be intimidated or driven out of business under any circumstances...
