Robert Hardy and Helen Mirren star as Benito Mussolini and Claretta Petacci who spend their last night locked together in a small peasant cottage by Italian partisans.

During the course of their party, couples form and love blooms as they socialize, insulated from the seismic events unfolding in the world around them. In The Philanthropist Helen Mirren appears in a showstopping performance as Philip’s fiancée Celia.

The Little Minister (1975)
Helen Mirren plays Babbie, a mysterious young gypsy girl who incites a Luddite riot in rural 1840’s Scotland.
