Although this claims to be an ‘Ultimate Edition’ re-release, only Rocky I has been given the UE treament. Fans may have already purchased the original ‘25th Anniversary 5 Disc Set’ edition, and might be considering upgrading to this new release. Heres some friendly info, While Rocky I has a couple new commentaries, and a few more featurettes, Rocky II,III,IV and V, are the exact same release as the previous editions. No picture remastering here, and no superiour audio tracks either. Even the DVD menus are exactly the same.
Your seriouslly better off just spending $29 and buying Rocky I ‘Definitive Edition’ by itself, and keeping your original box set.
The cover of the box has this ‘State-of-the-art Picture and Sound’. Which would lead you to believe all 5 films have been remastered. Sorry MGM/FOX, you'll have to do better than that.
