"Boxing Bloopers" is a 90-second short film, actually a collection of clips and judging from the title it really could be anything. But this is part of the Rocky universe as in here you will find a few scenes gone wrong but funny during shooting from the 2006 film Rocky Balboa. You see Sly Stallone of course and some other cast members. I personally haven't seen Rocky Balboa yet because I'm not a big fan of the franchise, especially the overrated first film, but these snippets here also don't get me particularly curious I must admit to watch it anytime soon. That's why all in all I give it a thumbs-down. Not a failure, but also way belov the level of quality where I would recommend checking it out. Go for something else other than this DVD/Bluray add-on.
