I agree with Nite Owl. Isn't Captain America still Paramount, or is this one Disney? Because if it's still Paramount then TF3 and Captain America were both from the same studio, switching dates couldn't have been that hard. Captain America gets the 4th of July weekend and Transformers opens at the very end of Summer with very little competition and still makies bank. It would have made more sense.
Really sucks Transformers is hogging all the screens this weekend. It would've been the perfect time to release the movie.
