Javier Espada explores how Luis Buñuel, one of the greatest precursors of surrealist cinema through works like ‘An Andalusian Dog’ and ‘The Golden Age’, began to move awayfrom this movement but never completely abandoned it, maintaining a strong oneiric element in his film career in Mexico and later in France and Spain. Taking us deep into his past and evolution as a creator, this documentary provides an unprecedented window into the world and work of an irreplaceable genius whose influence hasreached the rest of the arts.
