Pitfall (おとし穴, Otoshiana), a.k.a. The Pitfall and Kashi To Kodomo, is a 1962 Japanese film directed by Hiroshi Teshigahara, written by Kōbō Abe. It was Teshigahara's first feature, and the first of his four film collaborations with Abe, the others being Woman in the Dunes, The Face of Another and The Man Without a Map. Unlike the others, which are based on novels by Abe, Pitfall was originally a television play called Purgatory (Rengoku). The film has been included in The Criterion Collection. It is known for its surreal, often avant-garde storytelling structure and themes of hopelessness, exploitation, and human suffering.
