Mexican actor Gael García Bernal said in Washington that U.S. authorities should find alternatives to building more barriers along the southern border, a measure he called an expression of "ignorance."

"The walls will fall one day, absolutely," he said on Tuesday evening upon accepting a Human Rights Award from the Washington Office on Latin America.

García Bernal received the WOLA prize in recognition of his commitment to migrants, particularly his work on "Los Invisibles," a quartet of short films about the experiences of immigrants from Central America and the rest of the region en route to the United States through Mexico.

"Come on, we never thought we'd be here" receiving the award in the Organization of American States headquarters, said an emotional García Bernal referring to friend and fellow actor Diego Luna.

Luna received his own award along with the rest of the Ambulante documentary-film group, which he founded in 2005 with García Bernal and producer Pablo Cruz.

In addition, Cedeco, which promotes the development of sustainable agriculture in Costa Rica, received one of the annual awards from WOLA, which works to foster democracy and human rights in Latin America.

García Bernal, Mexico's biggest film star, participated in the "Los Invisibles" project at the invitation of Amnesty International.

On Thursday, "Los Invisibles" will be presented during an event in Congress convened to discuss the current situation of immigrants' rights.
