I do have a feeling that the trailer has been released too early and not officially by Universal. I would have thought the guys making the film would tell the actors when they were releasing a trailer (Felix Avitia would have almost definitely posted it to his Facebook page if he knew, and Aria Curzon didn't know about it, either), and that they would release it with another film. The only films I know of that are coming out for LBT's target audience are the new Thomas and Barbie films coming out in September. Plus, if Universal was going to officially release the trailer, why not just put it on YouTube rather than Rotten Tomatoes of all places? The timing and the way this trailer was uploaded seems rather strange to me...
Now, about the "We'll never make it through!" line. I always thought that it was Cera speaking, and honestly, I never even thought about Ruby. Now that I've gone and looked at an episode where Ruby does quite a lot of speaking, and I've listened to that line a couple of times again, I'm honestly not sure who it is right now... What throws me off is that a split second after the line is said, it shows Cera with an open mouth. I guess we'll find out when the film is released. :blink:
