HBO has released a 15-minute trailer for Season 4 of "Game of Thrones."

The biggest takeaway? "Some of the most shocking, mind-blowing scenes of the entire series come from the end of this season," said David Benioff, co-creator and showrunner for the series.

With a mix of scenes from the upcoming season and interviews from the cast and the crew, it seems it's going to be more dramatic and enthralling than before. The cast promises the action will happen quicker because there are more pivotal moments, unlike other seasons where episode nine has had the biggest shockers.

After last season's jaw-dropping "The Rains of Castamere," nicknamed the Red Wedding, the world is falling apart.

We see clips of Arya Stark training to become a better fighter. Jon Snow struggles after abandoning Ygritte, and Tyrion Lannister is going to have a tough season. "He's never had this much public humiliation," said Peter Dinklage about his character. "He usually has an answer for it."

There's also a peek into Joffrey Baratheon's wedding, and it's exactly as "ostentatious" and "grand" as you would expect.

Another person having a tough go at it is Daenerys Targaryen. "How can I rule Seven Kingdoms if I can't control a single city," she says.

But she's still full of the same spunk that made people fall in love with the character, also saying, "They can live in my new world, or they can die in the old one."

The cast also answers fan questions throughout the teaser. From the craziest thing they have done to who their favorite characters are, the actors open up about their experiences.

Not surprisingly, they aren't Joffrey fans. Jack Gleeson, who plays the ruler of the Seven Kingdoms, responds by saying, "It's nice to make people hate you."

"Game of Thrones" returns April 6.
