The 60-second teaser for Alfonso Cuaron’s upcoming Netflix film Roma contains a single frame: soapy water constantly spurts on to spotless floor tiles, where a reflection of an airplane is briefly seen.

Set in Mexico City in the early 1970s, the film revolves around two domestic workers Cleo (Yalitza Aparicio) and Adela (Nancy García García), who work in a middle-class neighbourhood in the Roma district. Cuaron, the first Mexican filmmaker to win an Oscar award for Gravity (2013), revealed in an interview with Indie Wire that Roma came from a very personal space.

“Ninety percent of the scenes represented in the film are scenes taken out of my memory,” Cuaron told the website. “It’s about a moment of time that shaped me, but also a moment of time that shaped a country.”

Cuaron, whose films including A Little Princess (1995), Y Tu Mamá También (2001) and Children of Men (2006), has also handled the cinematography for Roma after his frequent collaborator Emmanuel Lubezki dropped out from the project.

Roma will have its world premiere at the Venice Film Festival in August. The film’s release date is yet to be fixed.
