In the US, both the DVD and Blu-ray release contain the Theatrical Version as well as an Extended Cut. Since Warner Bros. don't release Unrated Versions anymore, the Extended Cut got an R by the MPAA as well. Contentwise, the 8 additional minutes offer more sleazyness so the missing "Unrated" term shouldn't be overrated. Around 30 differences can be found and a detailed comparison between both versions with pictures is available here.
