Darling Lili (1970)

With a somewhat convoluted story, Julie Andrews tries to shed her pure Mary Poppins image by portraying a German spy during World War I who also engages in the occasional striptease. American pilot Rock Hudson flies in as her target and love interest. The tone of the extravagant production matches the story, jumping from comedy to romance to musical to spy flick, moving from one to the next with little sense of flow.
