The British Board of Film Classification (BBFC) has released the UK rating and running time of the next trailer for Transformers: Age of Extinction. The time is 2 minutes, 25 seconds with a 12A (aka PG-13) rating. No clue on when the next trailer will hit theaters and the web but Amazing Spider-Man 2 (5/2) seems like the best candidate with X-Men: Days of Future Past (5/23) a good second choice.
