Oldboy (2013)

Parents need to know that Oldboy is Spike Lee's remake of the extremely violent Korean movie of 2003. This retains the violence and deals with dark, subversive ideas as part of their plots. The character becomes a fighter, and beats up several people (sometimes using a hammer as a weapon). He's stabbed in the back. Characters are tortured, shot, and killed, and commit suicide, and there's an attempted rape. There's a graphic sex scene with female toplessness and male and female backsides shown, plus some other unsavory sexual elements central to the movie's story. Language is also strong, with many uses of "f--k" and "s--t." The main character begins the story as a hardcore alcoholic, though he recovers. Many savvy teens will already be aware of the original film, a much loved cult classic, and the new one does not change much of the basic plot. But many curious teens will want to see this new version, especially if they don't care for subtitles.
