In Agatha Christie's Poirot, The Underdog, a portrait painted by the artist Tamara de Lempicka in 1928 has been copied and the face altered to resemble the actor who plays the character Reuben Astwell. Tamara de Lempicka was a famous female artist of the Art Deco era and her works typify the style of the period.
Another example is a portrait from the episode One, Two, Buckle my Shoe that borrowed heavily from two different painting by Tamara de Lempicka.
The boardroom scene in one,Two Buckle my Shoe features a portrait of a couple which was based on two separate portraits by by Tamara de Lempicka as seen below.
Seen in Lady Violet's dower house on Downton Abbey, a statue of Giambologna's Flying Mercury, the Greek messenger of the gods.. Mercury is depicted wearing a winged petasus on his head and winged sandals which give him speed in flight. He carries the caduceus in his hand, a wand given to him by Apollo.
I recently watched the documentary Tim's Vermeer, and highly recommend it, even if you are not all that interested in art. It is a fascinating documentary film about an inventor with no previous experience of painting, Tim Jenison, who decided to duplicate the painting technique of Johannes Vermeer (the painter of The Girl With the Pearl Earring) and his remarkable results. In the course of preparing to duplicate the masterpiece he built a replica of Vermeer's studio and recreated the contents of the room and lighting conditions seen in the original painting, and ground his own lens for his own version of the camera obscura.
The Original Work:
A Lady at the Virginal with a Gentleman, 'The Music Lesson'
