Death in Venice (Italian: Morte a Venezia) is a 1971 historical drama film directed and produced by Italian filmmaker Luchino Visconti, and adapted by Visconti and Nicola Badalucco from the 1912 novella of the same name by German author Thomas Mann. It stars Dirk Bogarde as Gustav von Aschenbach and Björn Andrésen as Tadzio, with supporting roles played by Mark Burns, Marisa Berenson, and Silvana Mangano, and was filmed in Technicolor by Pasqualino De Santis. The soundtrack consists of selections from Gustav Mahler's third and fifth symphonies, but characters in the film also perform pieces by Franz Lehár, Ludwig van Beethoven, and Modest Mussorgsky. Preceded by The Damned (1969) and followed by Ludwig (1973), the film is the second part of Visconti's thematic "German Trilogy".
