Show Caption Hide Caption Clip: 'Game of Thrones: The Complete Third Season' See a clip from the bonus feature 'The Rains of Castamere Unveiled, which offers an in-depth look at the series-altering 'Red Wedding' episode from 'Game of Thrones.'

A year ago, the phrase "Red Wedding" didn't mean anything to many of us. After Game of Thrones aired its pivotal episode "The Rains of Castamere," however, it became instantly familiar, even to people who don't watch the HBO drama.

In February Game of Thrones' third season arrives on DVD and Blu-ray. One of the bonus materials, The Rains of Castamere Unveiled, takes an in-depth look at the episode that altered the course of the series.

Today I have your first look at that feature as well as details about the set's other bonus material. While the video doesn't include any spoilers about what happens in the ep, it probably wouldn't make sense to watch it until after you've seen the season.

Bonus stuff on the DVD includes:

- "A Gathering Storm," a 14-minute recap of the second season;

- "The Politics of Marriage," where cast/crew examine the institution's place in the show;

- An "Inside the Wildlings" featurette;

- Another feature spotlighting new characters;

- Five deleted and extended scenes; and

- Twelve audio commentaries with the cast and crew.

The Blu-ray with HBO Select release includes all of the above as well as:

- An in-episode guide with character info and locations;

- The Rains of Castamere Unveiled

- The Roots of Westeros guide

- A "Histories & Lore" feature about the mythology of Westeros.

Game of Thrones: The Complete Third Season set goes on sale Feb. 18.
