It’s the first time the actor won’t be billed as Sheen. TMZ obtained this screengrab from the upcoming pic showing that he’s changed his name to Carlos Estevez for writer-director Robert Rodriguez’ upcoming campy thriller Machete Kills. Explanation: Sheen’s dad Martin Sheen was born Ramón Antonio Gerardo Estevez and never changed it legally to ’Martin Sheen’. So ‘Estevez’ is Charlie’s real last name just as it is Emilio’s. Machete Kills also stars Danny Trejo, Sofia Vergara, Mel Gibson, Jessica Alba, Antonio Banderas, Vanessa Hudgens and Lady Gaga whose big-screen debut came about because of a chance encounter with Trejo in an LA tattoo parlor. Pic is scheduled to be released in the U.S. in September.
