'Tis Pity She's a Whore (1980)

Lord Sorenzo marries the beautiful young Annabella, but unbeknownst to him, she is pregnant as a result of an incestuous relationship with her brother Giovanni. Sorenzo discovers the truth, and his ambitious, scheming servant Vasques, resorts to murder (and worse) to ensure that the whole affair ends in a heart rending tragedy! The original 17th century play was set in Italy, this version the action takes place in Victorian England.
