Mikhail Konstantinovich Kalatozov (Georgian: მიხეილ კალატოზიშვილი , Russian: Михаи́л Константи́нович Калато́зов ) (28 December 1903 — 27 March 1973), born Mikheil Kalatozishvili, was a Soviet film director of Georgian origin who contributed to both Georgian and Russian cinema.
 People's Artist of the USSR (1969).
 His movie "The Cranes Are Flying" won several international awards, including Palme d'Or at the 1958 Cannes Film Festival.
The 11th Cannes Film Festival was held from 2 to 18 May 1958.
 The Palme d'Or went to the "Letyat zhuravli" by Mikhail Kalatozov.
Pierre Chenal (] ; December 5, 1904 – December 23, 1990) was a French director and screenwriter who flourished in the 1930s.
 He was married from 1937 – 1955 to Florence Marly (2 June 1919 – 9 November 1978), a Czech-born French film actress.
The Cranes Are Flying (Russian: Летят журавли , translit.
 "Letyat zhuravli") is a 1957 Soviet film about World War II.
 It depicts the cruelty of war and the damage suffered to the Soviet psyche as a result of World War II (known in the Soviet Union as the Great Patriotic War).
 It was directed at Mosfilm by the Georgian-born Soviet director Mikhail Kalatozov in 1957 and stars Aleksey Batalov and Tatiana Samoilova.
 It won the "Palme d'Or" at the 1958 Cannes Film Festival, the only Soviet film to win that award, although "The Turning Point" (1946) was one of eleven films awarded that year's Grand Prix, the predecessor of the "Palme d'Or".
Hostile Whirlwinds (Russian: Вихри враждебные , "Vikhri vrazhdebnye " ) is a 1953 Soviet historical film directed by Mikhail Kalatozov based on a screenplay by Nikolai Pogodin.
I Am Cuba (Spanish: Soy Cuba ; Russian: Я Куба , "Ya Kuba)" is a 1964 Soviet-Cuban film directed by Mikhail Kalatozov at Mosfilm.
 The film was not received well by either the Russian or Cuban public and was almost completely forgotten until it was re-discovered by filmmakers in the United States thirty years later.
 The acrobatic tracking shots and idiosyncratic mise en scene prompted Hollywood directors like Martin Scorsese to begin a campaign to restore the film in the early 1990s.
True Friends (Russian: "Верные друзья") is a 1954 dramatic comedy film directed by Mikhail Kalatozov.
Letter Never Sent (Russian: Неотправленное письмо , translit.
 "Neotpravlennoye pismo", sometimes translated as The Unsent Letter or The Unmailed Letter) is a 1960 Soviet adventure drama film directed by Mikhail Kalatozov and starring Tatyana Samojlova.
 It was entered into the 1960 Cannes Film Festival, but was withdrawn just before the screening on May 17; according to the Soviet representatives, the film was "unfinished" (as a matter of fact, Kalatozov wanted to re-shoot some sequences before the premiere in Russia).
Salt for Svanetia (Georgian: მარილი სვანეთს , Russian: Соль Сванетии ) is a 1930 SovietGeorgian silent documentary film directed by Mikhail Kalatozov.
 As one of the earliest ethnographic films, it documents the life of the Svan people in the isolated mountain village of Ushguli in Svanetia, in the northwestern part of the Georgian Soviet Republic.
 Containing some propaganda, the climax of the film shows how a Soviet built road connects the previously isolated mountain village to Soviet civilisation.
 Many of the scenes of the film were staged, and the authenticity of some scenes has been disputed by the Svan people.
