Surrealism and Abstract Expressionism were influential art movements of the early 20th century. Surrealism drew inspiration from dreams and the unconscious mind. It used techniques like collage and photomontage to create bizarre and imaginative works. Leading Surrealists included Salvador Dali and Luis Bunuel. Their 1929 film Un Chien Andalou exemplified Surrealist ideals. Abstract Expressionism stressed spontaneity and conveying emotion through abstract gestures and brushstrokes. Pioneers included Jackson Pollock, known for his "drip paintings", Willem de Kooning who used slashing brushstrokes, and Franz Kline who built up thick textures. These styles also influenced Filipino artists
