It’s 100% legit. The movie was just added to Dianna’s IMDB today, as someone had just checked her page yesterday and it wasn’t there. Once the info was on IMDB, LiveLoveDianna emailed the director of the movie to try and get confirmation if this info was legit. Shortly after she emailed she replied back confirming she was indeed part of the cast. Sites began to update with Dianna’s info and then tonight, one of the directors, Alexandra Roxo, replied to a tweet about Dianna being Sarah, essentially confirming it. So at some point, Dianna replaced Imogen as the lead and Dianna will now be playing Sarah.
