Production is slated to begin on Fast and Furious 6 (that’s the working title for now) soon, and director Justin Lin looks to be adding a strong female presence for his Fast Five follow-up.  We learned last week that MMA fighter/Haywire star Gina Carano has entered talks to join the car-enthusiast ensemble, and now The Daily Mail claims that Rihanna is set to take on a villainous role in the pic.  It’s important to note that The Sun is a somewhat less-than-reputable source, so this casting news should be taken with a grain of salt for the time-being.The artist stars in this summer’s Battleship, but we haven’t seen much of her acting ability in the trailers so it’s hard to judge this casting choice, should it turnout to be true.  Remember Samantha Mumba in The Time Machine?  Oh, you don't?  Dwayne Johnson told Steve that they’ll be filming Fast and Furious 6 in London and Berlin, so we can look forward to an international vibe for the upcoming actioner.  The film is slated to open on May 24th, 2013.
