According to IMDB, it looks like Renesmee will be played by Mackenzie Foy. Although nothing is official until we hear word from Summit. For right now we can all assume that Renesmee will be played by Mackenzie Foy, age 9. Although some are skeptical, Bill Condon just released some masterminds that are going to bring this film together, Part 1 and Part 2. I am going to leave my comments to myself until further information is released. As a fan I am not sure how this going to come together but I have faith with the talent that is lined up that the best is yet to come....Please remember that Mackenzie is a little girl so everyone is entitled to their opinions lets just keep them clean!!
