Assassination Tango (2003)

Synopsis
Leading man Robert Duvall writes and directs his third feature, the romantic thriller Assassination Tango. John J. (Duvall) is an aging hit man who has settled down into family life in New York with teacher Maggie (Kathy Baker). After he is offered a good sum of money, he accepts a job to kill an Argentinean General in Buenos Aires. When he gets there, he finds out he has to wait three months to finish the job, so he stays in Argentina and studies the tango. He meets young dancer Manuela (real-life girlfriend Luciana Pedraza making her film debut) and the two become dance partners and lovers. It's not long before his newfound love affair conflicts with his original job duties. ~ Andrea LeVasseur, All Movie Guide
