Overview

• HBO Max Latinoamérica published the crossover video on October 10 to promote La Sustancia, which is now available to stream on the platform.
• The clip shows María Antonieta de las Nieves receiving a box marked “504,” reading a note that says “Ustedes son una misma,” injecting an activator, and meeting her younger self played by Paola Montes de Oca.
• Both actresses deliver Chilindrina catchphrases, including “¡Funcionó! Fíjate, fíjate, fíjate” and “No oigo, no oigo, soy de palo. Tengo orejas de pescado,” before sharing a lighthearted reconciliation.
• Paola Montes de Oca recently portrayed a young María Antonieta in the series Chespirito: Sin querer queriendo, a fan-driven comparison that informed the official collaboration.
• La Sustancia, directed by Coralie Fargeat and starring Demi Moore and Margaret Qualley, is a body‑horror thriller whose premise critiques ageism and the fixation on youth, and the promo’s tone drew enthusiastic, trending reactions across regional social media.
