Online rumors that pop star Rihanna will play a “super sexy dominatrix” in a remake of The Last Dragon seem premature at best. Sony Pictures is working on a reboot of the 1983 cult classic with Samuel L. Jackson, but the studio has yet to secure a director and isn’t yet ready to cast the role originally played by Prince’s protégé Vanity. A source involved with the production says Rihanna is definitely one of the names on their short list of African-American pop artists. But, the source insists, there have been overtures from many different people interested in starring opposite Jackson in the project. If the producers can hire a director in the next month, the film could start shooting as early as summer.
