From "The Lord of the Rings" trilogy to "The Adventures of Tintin: The Secret of the Unicorn", Peter Jackson's movies have always received a PG-13 rating, allowing families across the globe experience the fantastical adventures without any hesitation.

However, the family-friendly Jackson movies are about to change as the third part of "The Hobbit" trilogy, "The Battle of the Five Armies", is going to receive an R rating for mild violent scenes.

The theatrical cut of the "Five Armies" was already pretty violent, but without any blood or gore, and was still passable with PG-13 rating. Given that the extended edition has been given an R rating, it can be assumed that the movie will have significantly more violence and brutality. Whether it will be just a bit of splatter or some heavy action-packed sequences, can be found out only after the release. The edition will have 20 minutes of fresh footage, not shown in the original theatrical release, so fans can hope to experience something really good.

If that was not enough to keep the curiosity of the fans intact, the extended editions of all three instalments of "The Hobbit" trilogy will also be re-released in theatres this fall. The news broke out on 25 August after the Blu-ray version of "The Hobbit: The Battle of the Five Armies" extended edition was announced.

The "The Hobbit" trilogy's production companies -- New Line Cinema, Metro-Goldwyn-Mayer Pictures and Warner Brothers -- have announced that at an event, all the three movies will be played over the course of three evenings: "The Hobbit: An Unexpected Journey Extended Edition" on 5 October, 2015, "The Hobbit: The Desolation of Smaug Extended Edition" on 7 October, 2015, and "The Hobbit: The Battle of the Five Armies Extended Edition" on 13 October, 2015.

"We are excited to give fans the first chance to see the extended editions of this trilogy in cinemas. The incredible cinematography and action in each feature will be even better on the big screen and will give 'Hobbit' fans a chance to binge-watch as a community," Fathom Events CEO John Rubey told Variety. Fathom Events is the company that is organising the screening.

This would be the first time that "The Hobbit" fans will get to watch all three extended editions in theatres. "The Battle of the Five Armies" will also be premiered in the event. The director, writer and producer of the films may give an introduction before each screening.

Slash Film has reported that the movies will each run around 13-30 minutes longer than their original counterparts. The extended versions of the JRR Tolkien film adaptations will be shown in 500 theatres all over the United States.
