Mrs. Fitzherbert, also known as Princess Fitz and A Court Secret, is a 1947 black and white British historical drama film directed by Montgomery Tully and starring Peter Graves, Joyce Howard and Leslie Banks.

[2] It is an adaptation of the 1945 novel Princess Fitz by Winifred Carter Whilst promotional material summarises the plot as the love affair between a prince and a "commoner", Mrs Fitzherbert falls far short of the definition of a "commoner" and would best be described as "lower aristocracy".

George retreats into decadence and depression, acquiescing to a false rumour of an affair between Maria and the Duke of Bedford spread by Lady Jersey, finally repudiating Maria and accepting a political marriage with Caroline of Brunswick, though his first meeting with her goes badly.

The scene shifts back to the elderly Maria and Wellington discussing George's death, where he informs her that among his last words was "Marguerita", his pet name for her, proving he had not forgotten her.
