Filming for "House of Cards" season 5 has officially begun and cast members have been keeping fans up to date on line on the progress including some plot details.

Joel Kinnaman, who was introduced in the previous season as Frank Underwood's (Kevin Spacey) new rival Will Conway, is teasing more trouble for the president of the United States.

Will has clearly established himself as a formidable foe to Underwood and their rivalry is going heat up even more in "House of Cards" season 5.

Just recently, Kinnaman shared a photo of the front page of the script for the third episode of the upcoming season, and said that "s--- is about to go down."

Will is one of the people that Underwood will have to worry about when it comes to keeping his presidency. Like him, Will is hungry for power and will do everything to get as much as he could.

This will definitely be on display in "House of Cards" season 5 as the characters are expected to go toe to toe in their bid to win America's vote.

Previously, there were reports that Will is not the only one Underwood will have to contend with to keep the highest position in the land. His wife Claire (Robin Wright) is expected to betray him for the power.

Thankfully, Underwood will still have Doug (Michael Kelly) by his side to help him no matter what. As Kelly revealed in an interview with Deadline, his character has developed an addiction to Underwood.

The actor said that his addiction not only to Underwood, but also to the late Rachel (Rachel Brosnahan), whom he had a relationship with, is also what makes Doug tick. It looks like this will be further manifested in "House of Cards" season 5.

"I mean, at his core, he is a guy who just battles massive addiction. He was addicted to Rachel. He was addicted to Frank. He's addicted to the job. Everything for him is 100 percent. You know, he doesn't half-a-- anything," Kelly explained.

Considering that Rachel's death is on Doug, there's a reason to fear for Underwood's life or at least their alliance.

"House of Cards" season 5 premieres early next year on Netflix.
