Two more join Rodriguez’s next. Variety has word that Amber Heard (‘Motor City,’ ‘The Rum Diary’) is in talks to join Danny Trejo, Jessica Alba, Michelle Rodriguez and Mel Gibson on the cast of Robert Rodriguez’s sequel ‘Machete Kills.’ The sequel finds Trejo reprising his role of the titular blade wielding ex-federale, as he is drafted by the U.S. government to track an arms dealer (Gibson) through Mexico before he can launch a deadly missile. Heard will be taking the role of a manipulative assassin code-named Miss San Antonio. Also joining the cast will be Mexican actor Demian Bichir (‘Savages,’ ‘A Better Life’). Details on Bichir’s role are being kept under wraps for now. Production is slated to begin in the coming weeks in Austin, Texas.
