"Las Meninas" was produced by MF Films (a subdivision of Masoch Fund).  It was the first Ukrainian film to participate in the Tiger Awards Competition of the International Film Festival Rotterdam.

Infanta Margarita Teresa in a Blue Dress: Infanta Margarita Teresa in a Blue Dress is one of the best known portraits by Spanish painter Diego Velázquez.  Executed in oil on canvas, it measures 127 cm high by 107 cm wide and was one of Velázquez's last paintings, produced in 1659, a year before his death.  It shows Margaret Theresa of Spain who also appears in the artist's "Las Meninas".  Currently, the painting is in the Kunsthistorisches Museum.

José Nieto Velázquez: José Nieto Velázquez was the Queen of Spain's chamberlain and keeper of the royal tapestries.  He is the figure in the doorway in Diego Velázquez's painting "Las Meninas" and may have been a relative of the artist.

Self-Portrait with Palette (Manet): Self-Portrait with Palette (French: Autoportrait à la palette) is an 1878–79 oil-on-canvas painting by the French artist Édouard Manet.  This late impressionistic work is one of his two self-portraits.  Velasquez's self-portrait in "Las Meninas" was a particular inspiration for Manet's painting which despite its allusion to the previous artist's work is very modern in its focus upon the personality of the artist and loose paint handling.

Charles IV of Spain and His Family: Charles IV of Spain and His Family is an oil on canvas painting by the Spanish artist Francisco Goya who began work on this painting in 1800 and completed it in the summer of 1801.  It features life sized depictions of Charles IV of Spain and his family, ostentatiously dressed in fine costume and jewelry.  The painting was modeled after Velázquez's "Las Meninas" when setting the royal subjects in a naturalistic and plausible setting.

Margaret Theresa of Spain: Margaret Theresa of Spain (Spanish: "Margarita Teresa" , German: "Margarete Theresia" ; 12 July 1651 – 12 March 1673) was, by marriage, Holy Roman Empress, German Queen, Archduchess of Austria and Queen of Hungary and Bohemia.  Daughter of King Philip IV of Spain and elder full-sister of Charles II, the last of the Spanish Habsburgs, she is the central figure in the famous "Las Meninas" by Diego Velázquez, and subject of many of his later paintings.

Infanta Margarita Teresa in a Pink Dress: Infanta Margarita Teresa in a Pink Dress is a 1660 oil on canvas portrait of Margaret Theresa of Spain by the Spanish painter Diego Velázquez, though his identification as its author is not considered secure.  It is now in the Prado Museum in Madrid.

Las Meninas: Las Meninas (] ; Spanish for The Ladies-in-Waiting) is a 1656 painting in the Museo del Prado in Madrid, by Diego Velázquez, the leading artist of the Spanish Golden Age.  Its complex and enigmatic composition raises questions about reality and illusion, and creates an uncertain relationship between the viewer and the figures depicted.  Because of these complexities, "Las Meninas" has been one of the most widely analyzed works in Western painting.

Las Meninas (horse): Las Meninas (foaled 22 April 1991) was an Irish Thoroughbred racehorse and broodmare.  In a racing career which lasted from June 1993 to November 1994 she ran eight times and won two races.  As a two-year-old she won on her debut and finished second in the Phoenix Stakes at Leopardstown.  On her three-year-old debut, Las Meninas defeated Balanchine to win the Classic 1000 Guineas at Newmarket Racecourse becoming the first Irish winner since 1975.  She went on to finish second in the Irish 1,000 Guineas at the Curragh but her subsequent form deteriorated and she finished unplaced in her remaining four races.  Las Meninas was retired from racing to become a broodmare at the end of her three-year-old season.

Las Meninas (Picasso): Las Meninas is a series of 58 paintings that Pablo Picasso painted in 1957 by performing a comprehensive analysis, reinterpreting and recreating several times "Las Meninas" by Diego Velázquez.  The suite is fully preserved at the Museu Picasso in Barcelona and is the only complete series of the artist that remains together.  This is a very extensive survey work which consists of 45 performances of the original picture, nine scenes of a dove, three landscapes and a portrait of Jacqueline.
