The two are starring in The Duchess and I,  a British drama directed by Mike Newell that focuses on Wallis Simpson's final years living as a widow and recluse in Paris. Collins plays Simpson, who suffered from many illnesses and became increasingly incapacitated around 1978.  Rossellini plays Suzanna Blum, a French lawyer who assumed control of the Duchess's affairs after the Duke of Windsor's passing in 1972. Blum isolated Simpson from family and friends, dismissed her staff, and sold off valuable heirlooms to personal contacts both before and after Wallis's passing in 1986. Blum maintained that all actions reflected the Duchess's explicit wishes, though she often withheld any documentation of her authority.
