Enrique Álvarez Félix was the son of Mexican actress María Félix and her first husband, Enrique Álvarez Alatorre. When his parents divorced in 1938, his mother lived for a time at home with her own parents until 1939, when she traveled with Enrique to Mexico City. Soon after, her ex-husband took Enrique. He never married, but was a stepson of Jorge Negrete and stepbrother of Diana Negrete. According to Mexican novelist and essayist Carlos Fuentes, Álvarez Félix was purportedly sexually frustrated and had an Oedipus complex.
Álvarez's last acting role was "Leonardo" in Marisol. The title character, Leonardo's niece, was played by Erika Buenfil; Leonardo's wife, Ámparo, was played by Claudia Islas. He died two days after the episode in which his character, Leonardo, was killed off.
^Álvarez Félix's role as "Nilo" in La Casa del Pelícano is enduringly controversial. He played a son of raped woman, Margarita Ramírez (played by Jacqueline Andere). At the end of the film, Margarita castrates Nilo.[why?] Dictionary of Mexican Literature; edited by Eladio Cortes.
^Celluloid Nationalism and Other Melodramas by Susan Dever, pg. 185. "For spectators who followed national news reports about the late Enrique Álvarez Félix's allegedly difficult relationship with (his) real-life mother María Félix, it may be hard to ignore the irony of Álvarez Félix's character suffering castrating stabs."
