Amores perros is a 2000 Mexican psychological drama film directed by Alejandro González Iñárritu and written by Guillermo Arriaga, based on a story by them both. Amores perros is the first installment in González Iñárritu's "Trilogy of Death", succeeded by 21 Grams and Babel. It makes use of the multi-narrative hyperlink cinema style and features an ensemble cast. The film is constructed as a triptych: it contains three distinct stories connected by a car crash in Mexico City. The stories centre on a teenager in the slums who gets involved in dogfighting; a model who seriously injures her leg; and a mysterious hitman. The stories are linked in various ways, including the presence of dogs in each of them.
