María Antonieta de las Nieves (born December 22, 1950) is a Mexican actress of voice-over, film, and television; best known for her portrayal of "La Chilindrina" in the Televisa sitcom, El Chavo del Ocho (1973–1979). She has reprised her synonymous and diminutive character in film and television for over 20 years, which has caused tension and legal lawsuits between de las Nieves and Chespirito: the character's creator.

De las Nieves' film debut was at the age of 7 in the film, Pulgarcito (1957), starring Cesáreo Quezadas 'Pulgarcito'. A year later, she was cast as in a minor role in the first Mexican telenovela, Senda prohibida (1958) starring Silvia Derbez.

Prior to her work with Chespirito, she was a voice-over actress for Televisa. Among the many characters she dubbed for, the most recognizable are "Dorothy Gale" in The Wizard of Oz, "Eddie Munster" in The Munsters, and "Wednesday Addams" and "Pugsley Addams" in The Addams Family.

De las Nieves became famous as La Chilindrina in the Mexican Televisa television show, El Chavo del Ocho. She was also the lead actress on El Chapulín Colorado until 1973, when she left and Florinda Meza took over the role. She was a voice-over actress at Televisa, when Chespirito heard her talk. Thinking her voice was perfect for the Chilindrina character, he offered her a job at his new show, and she accepted. Both El Chavo.. and El Chapulín... became hits across Latin America, in New Zealand and the United States, as well as various other countries where the program was translated into local languages. The casts of Chavo and Chapulín toured extensively whilst the show was on; after cancellation of the show's filming in Mexico, its actors continued travelling, and the show continued to be featured in many Latin American countries (in the United States it is still, as of 2011, shown).

Carlos Villagrán Eslava (born January 12, 1944) is a Mexican comedy actor and former journalist. Villagrán combined both acting and writing at first; he became known for a character named Quico.

He went on to write for a local newspaper in Mexico City. As a writer, he became friends with screenwriter and future co-star Rubén Aguirre. Aguirre was hired by Chespirito (Roberto Gómez Bolaños) to play Professor Jirafales in the upcoming El Chavo del Ocho Televisa television series. Aguirre held a party for family and friends at his house, and Villagrán impressed him after expanding his cheeks out of proportion during one of the party's comic steps. As a matter of a fact, that movement would later become a trademark of the character he'd play in El Chavo.

Aguirre recommended Villagrán to Chespirito, and Villagrán was given the Quico character in the show. He also appeared on Chespirito's other hit show, El Chapulín Colorado. Both of Chespirito's shows became major international hits all over Latin America and in the United States, Spain, and other countries. Villagrán acquired great fame with these shows.

Florinda Meza García de Gómez (born February 8, 1949) is a Mexican actress of film and television; she is also a writer, director, and producer. She started her career when Roberto Gómez Bolaños cast her in El Chavo as "Doña Florinda". Meza is also known for her role of "La Chimoltrufia" in the sketch comedy Los Caquitos, and for various roles in El Chapulín Colorado, Los Chifladitos, and Dr. Chapatín.

Meza was cast by Roberto Gómez Bolaños to play "Doña Florinda" in the Televisa comedy show El Chavo, which became a major international hit. Playing "Doña Florinda" (and "Popis"), Florinda Meza became known all over Latin America. The show lasted from 1972 to 1980 (although the sketch would continue until 1992), during which she and Roberto began a life-long romance that never produced any children. During her tenure on the Chespirito show, she was also known to have played Edgar Vivar's character "Botija"'s wife "Maria Expropiacion Petronila", famously known as "La Chimoltrufia" Meza also participated prominently in Chespirito's other main show, El Chapulín Colorado. After production of the show Chespirito ended in 1995, she and Roberto began touring extensively, something they still do. The two Mexican actors got married in a civil ceremony on November 19, 2004, after 27 years of sharing their lives.
