Deleted scenes! They were filmed [scenes mentioned]
But i dont think all these scenes will make it to the dvd though, but if there was a extended poa dvd all scenes might be included but who knows maybe most/or all scenes mentioned might be edited into the film in the poa dvd and there might not even be an extended. Remember what cuaron said about the dvd already in works when he started filming the movie, so maybe tdone so he can have time to editing cut scenes and then add them into the film later.
