The History Channel renewed the series for a 10-episode third season on March 25 earlier this year.

Members of the cast and crew made apperances  during the San Diego Comic Con and gave an interview to Yahoo! TV a month ago, revealing a few details about the next upcoming season.

"It's only going to get grittier, and I think that's why fans are absolutely in love with it right now," said Alexander Ludwig, who plays Bjorn in the series.

Katheryn Winnick, who played Lagertha, said, "Season 3 is even more epic than Season 2. If you thought you loved Season 2, Season 3 just takes it to a whole new level," Winnick said.

"We had some shield maidens last year that went into full-on martial arts training just to understand how to hold a sword properly, just so they could be background actors," she added.

In the recent San Diego Comic-Con, series creator Michael Hirst revealed that the upcoming season will feature the biggest adventure that Lothbrok and his brave Viking warriors have faced yet: The Great Raid in Paris.

"Yeah, we're gonna attack Paris. Paris was the most extraordinary city. It was still a Roman city, and it was like nothing else on earth," Hirst confirmed during an interview with Collider.

The show creator also revealed that production of the Paris set is ongoing and that it will involve the use of CGI.

"We're just building that, at the moment, on the backlot. It will also be CGI," he added.

"We go back to the raiding thing this year instead of all the dramas in Kattegat," Fimmel was quoted saying in an interview. "So, we'll be back together raiding."

Several new actors will be joining the cast of "Vikings" for season 3, including: Lothaire Bluteau as Emperor Charles of France; Jennie Jacques as Judith, mother of Alfred the Great; and French actress Morgane Polanksi as the Emperor's daughter Princess Gisla.

TV Guide also revealed other mysterious characters who will add more excitement to the drama. There's Harbard, who will catch the attention of Siggy, Aslaug and Helga, and Kalf, whom the Shieldmaiden Lagertha (Katheryn Winnick) has entrusted her dominion with while she sailed off alongside Ragnar.

Another interesting spoiler that has emerged concerns the death of a fan-favorite character. Even though it has not yet been revealed who is going to die in the next installment, actor Kevin Durand spoke to Entertainment Tonight Canada about it.

He said, "Do you know how that happens? Did you know that I was there? When the person dies ...yeah, I'm on Vikings... it might have been my fault..." Durand said

Durand told interviewers revealed that he will be playing mysterious wanderer character, he can either be a wreak havoc or be a poet.

"Vikings" season 3 is currently in production and expected in the Summer of 2015.
