Its release in Los Angeles theaters Friday, and nationwide next week, coincides with a US presidential election in which both sides have vied for Latino votes, and migration has been a fiercely contested issue. In recent days, an off-color joke by a comedian at a New York rally for Donald Trump, calling the US territory of Puerto Rico a "floating island of garbage," has caused particular controversy.
