It drew its inspiration in large measure from the life of Pierre Seel, an Alsatian homosexual deported to the camp of Schirmeck, who wrote of his experiences in a book, "Moi, Pierre Seel, déporté homosexuel".  The film won the Prix Jean Vigo in 2009. L'Atalante (] ; also released as Le Chaland qui passe, ("The Passing Barge"), is a 1934 French film written and directed by Jean Vigo.  Jean Dasté stars as Jean, the captain of a river barge who lives with his new wife Juliette (Dita Parlo) on the barge, along with first mate Père Jules (Michel Simon) and the cabin boy (Louis Lefebvre). La France is a French film directed by Serge Bozon, released in 2007.  It stars Sylvie Testud and Pascal Greggory.  The film won the Prix Jean Vigo in 2007. Richard Edmund Williams (born March 19, 1933) is a Canadian–British animator, voice artist, and writer, best known for serving as animation director on Disney/Amblin's "Who Framed Roger Rabbit" and for his unfinished feature film "The Thief and the Cobbler".  He was also a film title sequence designer and animator; his most famous works in this field included the title sequences to "What's New, Pussycat? " (1965) and "A Funny Thing Happened on the Way to the Forum" (1966) and title and linking sequences in "The Charge of the Light Brigade" (1968).  He also animated the eponymous cartoon feline for two of the later "Pink Panther" films. Jean Vigo (] ; 26 April 1905 – 5 October 1934) was a French film director who helped establish poetic realism in film in the 1930s; he was a posthumous influence on the French New Wave of the late 1950s and early 1960s. À propos de Nice is a 1930 silent short documentary film directed by Jean Vigo and photographed by Boris Kaufman.  The film depicts life in Nice, France by documenting the people in the city, their daily routines, a carnival and social inequalities.  Vigo described the film in an address to the Groupement des Spectateurs d'Avant-Garde: "In this film, by showing certain basic aspects of a city, a way of life is put on trial... the last gasps of a society so lost in its escapism that it sickens you and makes you sympathetic to a revolutionary solution." Poetic realism was a film movement in France of the 1930s.  More a tendency than a movement, poetic realism is not strongly unified like Soviet Montage or French Impressionism but were individuals who created this lyrical style.  Its leading filmmakers were Pierre Chenal, Jean Vigo, Julien Duvivier, Marcel Carné, and, perhaps the movement's most significant director, Jean Renoir.  Renoir made a wide variety of films some influenced by the leftist Popular Front group and even a lyrical short feature film.  Frequent stars of these films were Jean Gabin, Michel Simon, Simone Signoret, and Michèle Morgan. Jean Taris, Swimming Champion (French: Taris, roi de l'eau or La natation par Jean Taris, champion de France or Taris, champion de natation) is a 1931 French short documentary film directed by Jean Vigo, about the French swimmer Jean Taris.  The film is notable for the many innovative techniques that Vigo uses, including close ups and freeze frames of the swimmer's body. Blondel de Nesle – either Jean I of Nesle (c. 1155 – 1202) or his son Jean II of Nesle (died 1241) – was a French trouvère.
