(FYI this is the convention they are talking about NOT the premiere)
They say all good things must come to an end and so it is with our three year long The Twilight Saga: Official Convention Tour which has visited cities across The United States and Canada. Along the way we've met tens of thousands of fantastic fellow fans and it has been a particular joy celebrating the unprecedented success of the films and novels and working with so many talented and gracious stars. The passion and dedication of Twilight fandom has been amazing and we're out to throw one last giant convention, a final gathering to see old friends that have made up the Twilight family.
Although Rob, Kristen and Taylor will not be with us this time out we will have a super line-up of other Twilight stars and the weekend will be filled with special events, movie prop and costume displays, contests, panels, auctions, parties, exclusive merchandise, music and much more, including some surprises!
The last chapter in the film series, The Twilight Saga: Breaking Dawn Part 2 opens in America on November 16th, just a few weeks after the convention. So with excitement and anticipation in the air we invite YOU to be part of the fun…. make your plans to be with us NOW! for the wrap-up event of "The Tour!"
