So I decided to bite on this at the £19.99 price point. I've seen all the movies apart from The Last Knight, so that was the one I was most keen to watch. Turns out this six-disc set contains the first four movies, plus the bonus disc for Age of Extinction and the bonus disc for The Last Knight. There is no fifth movie. Not only that, but the bonus disc for The Last Knight has no sound. Does anyone else have this issue or is it just a one-off mistake? In any case, this is going back to Zavvi.
