The previous "Die Hard" films were rated "R" while this one was edited down to a "PG-13" rating which came as a surprise and shock to most people. Fox especially have had a record of re-releasing titles as unrated or "R"-rated cut DVD editions such as Alien vs. Predator, Daredevil and Mr & Mrs Smith. Also, Justin Long has said in interviews that alternate takes were filmed in some scenes that would be held back for future use in a possible "R"-rated or unrated version of the film. Further evidence for the possibility of an unrated Die Hard 4 DVD was the numerous moments when character's mouths moved but they didn't say anything, or they said something that doesn't match their mouth movements. An unrated DVD became available on November 20th, 2007, either by itself or with a second disc of bonus features. The Blu-ray releases of Live Free or Die Hard and the "Die Hard Collection" do not include the unrated version, as these discs were authored before work on the unrated cut was finalised. Edit
