If you don’t already find yourself frothing at the mouth for Game of Thrones‘ return on Sunday, April 6th, then the HBO marketing team are doing something wrong. Since the beginning of the year the network has been diligent in never letting a week go by without sharing new images, teasers, trailers, and a bevy of behind the scenes featurettes.

This week is no different, and following a couple of new teasers this past week, today the Game of Thrones‘ YouTube account uploaded four new featurettes. It’s been an interesting and no doubt successful strategy for HBO, releasing all these videos which could so easily have been saved for exclusive DVD/Blu-ray content. And it’s a strategy I’m surprised more television shows haven’t been enacting.

Above, in the first of these new featurettes, members of the cast and crew discuss the series upcoming nuptials, dubbed “The Purple Wedding”. Something to note from this video are the episodes director Alex Graves is directing – 2, 3, 8 and 10 – which gives the impression Joffrey’s and Margaery’s wedding likely happens over the course of episodes two and three. It will also be a lavish spectacle, very much in contrast to last season’s somber and tragic affair, “The Red Wedding”.

The following featurette examines the weaponry and training required to bring all of Game of Thrones‘ thrilling battles to life. There’s a bit of a chat with Maisie Williams and Rory McCann discussing their training, Kit Harington and Rose Leslie in the middle of the clash between wildlings and Night’s Watch men at The Wall, and a look at newcomer Oberyn Martel’s (Pedro Pascal) viper-themed spear. (Something we’ve seen in action in just about every teaser and trailer.)

Unsurprisingly, the longest of these featurettes focuses on the series’ tremendous costumes. Costume designer Michelle Clapton has really outdone herself this season with these marvelous new designs. Featured within is Margaery’s stunning wedding dress, Brienne’s new armor, Jaime’s latest accessory, as well as another look at Oberyn and Daenerys’ growing wardrobe.

Last but certainly not least we have a chance to hear from this season’s directors: Graves, Michelle MacLaren, Alik Sakharov, and Neil Marshall. Each have directed episodes of Game of Thrones previously, most notable however is Marshall who helmed season 2’s epic “Blackwater” and is back again for another intense episode centered on a major battle from the series.

There’s no question a good majority of Game of Thrones‘ success can be chalked up to the series’ impeccable world building and incredible attention to detail. When watching an episode of Game of Thrones, there’s never any doubt what you’re seeing could have believably existed in a bygone land. HBO must know this, which why they’ve made such a habit of giving fans a peek behind the curtain before their newest season even airs.

Game of Thrones season 4 premieres on Sunday, April 6th @9pm EST on HBO.
