Gael Garcia Bernal is using his filmmaking skills to address the problem of illegal migrants in Mexico.
The Letters To Juliet star features in Six Out Of Ten, one of four short films making up The Invisibles, which highlight the plight of these "invisible victims" - foreigners travelling in dangerous terrain through his home country without legal permission.
Gael, who, with Amnesty International, aims to improve protection for the migrants, talks to three women from Honduras who are travelling in search of a better life for their families. They are taking a huge risk, as six out of 10 women who attempt the journey are sexually abused.
"The Mexican authorities must protect migrants in our country," he said in a statement.
"The law must protect us all, whether nationals or foreigners. It's essential Mexico sets a good example in the way it treats migrants to be consistent with the valid demands we make for the fair treatment of migrants in the United States."
The other shorts include Seaworld, which was filmed at a migrant shelter in southern Mexico, What Remains following a mother in El Salvador desperate to know what has happened to her son 10 years after he left for the US, and GOAL! documenting the dangers and risks the migrants face.
Viewers will be able to watch the films and take action online at www.youtube.com/invisiblesfilms from November 8.
