Plot

Cantinflas, a penniless urban rogue, sneaks into the mansion of the businessman Cayetano through his girlfriend Paz, who works there as a maid. Before she lets him eat, Paz demands that he kill the family dog Bobby, which has suddenly gone mad with rabies. Trapped in the house when Cayetano returns early, Cantinflas is hidden alongside Bobby, the ex-boyfriend of Cayetano's wife Dolores, who has come to blackmail her. When Cayetano searches for his wife's supposed lover, Bobby escapes and only Cantinflas is found.⁸

Dolores then claims that Cantinflas is her long-estranged brother Leonardo, and Cayetano, who wants more of his wife's family inheritance, treats him lavishly. Trouble arrives when Leonardo's partner Clotilde (Sara García) shows up with their sons to press the inheritance and marriage questions, and the police come looking for Leonardo, who is accused of having killed a man named Bobby. Cantinflas confesses to having killed Bobby, meaning the dog, and is put on trial. The real Leonardo finally appears and reveals that he killed Bobby the man because he was being blackmailed; Cantinflas goes free and returns to waiting outside the mansion for food.⁸^•⁴

The trial scene and the cantinflesco language

The courtroom sequence is the film's centerpiece. It pushes to the extreme the confusion between the death of the rabid dog Bobby and that of the criminal Bobby el Fox-Terrier, and it showcases Cantinflas's trademark: an incoherent, endless torrent of words full of double meanings and false exits that wears down his opponents. In the film he even gets the judge and the prosecuting attorney talking nonsense on his level in spite of themselves. When everything is finally resolved and everyone ends up "cantinfleando", Cantinflas closes with the line: "ora sí, ¿lo ven?, todo aclarado; si hablando en cristiano se entiende la gente; ¿o no?".⁴^•⁵

According to SensaCine, director Juan Bustillo Oro based the final trial on the real 1925 trial of the criminal Álvaro Chapa.⁶ The verbal style on display gave Spanish the verb cantinflear, to talk a great deal while saying nothing of substance, along with the related words cantinflada and cantinflismo, later accepted by the Spanish Royal Academy.⁹^•⁵

Production and context

Bustillo Oro, a former law student who had directed his first sound feature, Dos monjes (1934), had consolidated his career with En tiempos de don Porfirio (1939). With Ahí está el Detalle he and co-writer Gómez Landero fused cinema with the verbal theater of the sainete, the zarzuela, and the género chico, and the film brought together for the only time a trio the trade press regarded as exceptional: Bustillo Oro as a specialist in dialogue-based humor, Joaquín Pardavé as an emblem of sophisticated revista-theater comedy, and Cantinflas, whose peladito (Mexican urban rogue archetype Cantinflas personified), an urban rogue with nothing to lose, defeats his enemies by intellectual exhaustion through the abuse of language.⁴^•¹⁰

Cantinflas had spent years developing the peladito character in traveling tent shows called carpas, taking his stage name from a heckler's shout, and had appeared in shorts and features from 1936 onward, with five advertising shorts made between 1939 and 1940. By 1940, with producer Jesús Grovas hiring established stars Pardavé and Sara García as his supporting cast, he was ready for his first feature. SensaCine counts Ahí está el Detalle as his eighth film, while the Ministry of Culture and Turner Classic Movies describe it as his first feature-length starring vehicle; the difference reflects earlier short subjects and supporting appearances.⁵^•⁷^•³^•⁴

The film belongs to the start of the Golden Age of Mexican cinema. Where only 29 films were made in Mexico in 1940, the number rose to 37 the next year and passed 100 by the end of the decade, a growth to which Cantinflas and other local comedians who achieved stardom in the period contributed substantially.⁵

Reception and legacy

The premiere was an immediate success, and the public made Cantinflas its idol from that moment. The writer Carlos Monsiváis considered it the first great comedy of Spanish-language cinema, and the film is widely treated as the work that elevated Mario Moreno to a star of continental reach; Turner Classic Movies credits it with making him an international star and his country's answer to Charlie Chaplin, who later called him "the world's greatest comedian".¹¹^•¹⁰^•⁴^•⁵

Despite that standing, the three principals never worked together again. Cantinflas preferred Alejandro Galindo for Ni sangre ni arena (1941), and on that shoot he met Miguel M. Delgado, then an assistant director, who became his regular director from El gendarme desconocido (1941) onward.⁴ Critics have read into the film an irony directed at the hypocrisy of the upper classes, as well as treatment of themes close to taboo in the Mexico of its day, such as women's powerlessness before mistreatment and harassment by men.¹²
