Amalgama

Watch 'Y TU MAMA TAMBIEN' and wait for the reference. There is a scene in that film during the road trip where they're passing through a military checkpoint and on the radio there is an ad for a dentist who can fix bad teeth using 'Amalgama', Also in that film, Luisa, the attractive Spanish woman is a dentist. I'm not sure what the deeper connection is regarding dentistry I would love to find out.

The beach they go to in 'Y TU MAMA TAMBIEN' is 'Boca del Cielo' and the beach they travel to in 'AMALGAMA' is 'Isla Cielo'.

The Cuaron brothers are bizarrely genius film makers and I love their dark humor and the way they celebrate Mexican culture but also make fun of its hypocrisy and idiosyncrasies.

Their photography is unique because they regularly take shots with multiple characters in the frame but also highlight beautiful scenery. So they rarely use close or tight shots. This is the case with both films.

Also if you haven't seen 'Rudo y Cursi' you need to..it is the funniest Mexican film that exists to my knowledge.
