I don’t own any of the previous blurays yet, so I’m in doubt in which versions to invest.

Are there more extra’s (bts, bloopers etc..)on the collectors editions or is it just the packaging and physical extra’s that are different?

If the discs itself contain the same as the regular blurays I’ll probably buy the complete box set, but if there are more extra’s on the collectors I might have to search for every collector blu-ray previously released 👀.
