There's a lot of hope riding on the renewal of "Bodyguard" for a second season. Its star, Richard Madden, who is most familiar to TV fans as Robb Stark from "Game of Thrones," has been openly talking about the show's potential return even as there has been no confirmation from the network as of press time.

Madden recently spoke to Ellen DeGeneres about the show's success. After she congratulated the actor on the incredible ratings and the two Golden Globes nominations for "Bodyguard," DeGeneres asked Madden about the second season.

He was excited to say that there have indeed been talks between him and those involved in putting the drama together. But because of the whirlwind surrounding the show's promotions, the holiday preparations and the awards season, Madden said that they have not sat down to begin work on "Bodyguard" season 2. He's hopeful, however, that after the frenzy has died down, then they can start brainstorming ideas for the new installment.

Series creator Jed Mercurio hinted that if the show were to get a green light, it could potentially go on for three more seasons. But Mercurio is also working on the fifth season of "Line of Duty," which haven't finished production in the U.K. The writer said that, if lucky to be approached and renewed by BBC, then work on "Bodyguard" season 2 won't happen until mid-2019.

"Bodyguard" features Madden as David Budd, a former war veteran and police sergeant who was assigned to protect Home Secretary Julia Montague (Keeley Hawes). Budd suffered from post-traumatic stress disorder (PTSD) and became embroiled with his boss despite hating her kind of politics.

In the last moments of "Bodyguard" season 1, viewers saw that Budd finally went to see a therapist for his PTSD. But whether or not he's back to protecting another VIP is still anyone's guess. It could be the plot point for "Bodyguard" season 2.

The show delivered several jaw-dropping scenes that made "Bodyguard" the point of water cooler discussions week after week. It became the highest rated drama series in the U.K. since "Downton Abbey," as per The Guardian.

Meanwhile, "Bodyguard" had also earned quite a following when it started streaming on Netflix for viewers outside of the U.K. Thus, the show came under the radar of more viewers and even the international press thus receiving some awards and recognition.
