The move comes in contrast to Sheen's earlier statement that he doesn't feel a Latino anymore.
The 47-year-old 'Two and a Half Men' star's dad was born as Ramon Antonio Gerardo Estevez, that he changed to Martin Sheen to get acting jobs but never changed it legally, reported TMZ Online.
A screen shot from the upcoming film shows Sheen using his birth name, Carlos Estevez.
The film is directed by Robert Rodriguez. Rodriguez films often celebrate Latino pride as his earlier films were titled as "El Mariachi", "Desperado".
