In early 2009, Milly joined eleven other Dominican music legends on a national tour celebrating the merengue and bachata music traditions of the country. That tour was transformed into a Felix Limardo documentary entitled Sol Caribe. The movie features an original song, La Puerta del Nuevo Mundo that is a once-in-a-lifetime collaboration of the twelve stars. The film was the closing feature at the III Dominican Republic Global Film Festival in November 2009 and was attended by the President of the Dominican Republic.
In addition to the Cassandra Awarded movie, "Yuniol 2" Milly has played important roles in the movies: “Cal y Arena,” Puerto Rico; “Hermanos R.D.” in Dominican Republic and the soon to be released movie “Juanita” written produced and directed by Leticia Tonos and which will be released in December 2018.
