The stars of Oscar-nominated film Y Tu Mama Tambien (And Your Mother Too) have said they will use cinema to highlight "injustices" in their native Mexico.

Diego Luna and Gael Garcia Bernal held a gala dinner as a way of raising money to support human rights causes.
And they promised to make documentaries raising awareness of issues such as the unsolved murders of more than 300 women in the border city of Ciudad Juarez.
"Each day it's harder to live in this country," said Luna.
And Garcia Bernal described how "documentaries show us the injustices in the country where we live, that this problem exists".
He added: "We can't escape it."
Tickets for the dinner, held on Saturday evening in Mexico City, were sold for $300 (£149) each.
Proceeds will go to Mexico's Commission for the Defence and Promotion of Human Rights.
They will also be given to Witness, an organisation founded by singer Peter Gabriel which promotes the use of video and film to document human rights abuses.
The actors have publicly supported other social and political causes, such as Mexico City's new law making gay civil unions legal.
Garcia Bernal also criticised a proposed border fence between Mexico and the United States, saying last year that the idea was "absurd".
