Celebrity-news Web site TMZ.com published a shot from the film, to premiere September in the US, which shows Sheen carrying an assault rifle while a super on the screen says "and introducing Carlos Estevez".
Charlie's dad, Martin Sheen, the son of a Spanish immigrant to the US, was born Ramon Antonio Gerardo Estevez. He called himself Martin Sheen to get work as an actor, but never legally changed his name.
Martin Sheen starred in the 2011 movie "The Way", directed by his son Emilio Estevez, the story of a Californian ophthamologist who goes to France when he learns that his son died in a storm in the Pyrenees. After discovering that the young man was going to make a pilgrimage on the Way of St. James to Santiago de Compostela, he decides to take his place, carrying his ashes.
It was in July last year that Charlie Sheen said he didn't feel Latino.
"I'm not ashamed of it, I'm not escaping from it, but I was born in New York and grew up in Malibu - that's not very Latino," Sheen said in an interview that aired on Univision.
"I'm a white guy in America," said the actor, who changed his name from Carlos to Charlie when he was 4 years old to avoid confusion with his Uncle Carlos, while the switch from Estevez to Sheen happened when he became an actor.
"I just don't get up feeling like a Latino," said the younger Sheen, whose Spanish grandfather died before he was born.
