Warning: This story contains major spoilers for the sixth and final season of House of Cards.
House of Cards delivered a doozy when it revealed Doug Stamper was the person behind Frank's demise. Yes, Frank was killed by his biggest fan and closest confidante, who ended up getting killed off himself before it was all said and done. Actor Michael Kelly revealed his reactions to those killer twists, saying this when asked if he was warned about Doug taking Frank out early on:
Fans knew that Frank Underwood was a goner before Season 6 premiered. That confirmation came via a promotional clip for the political drama's final season. The revelation that Stamper killed Frank was onething that fans were harder pressed to have imagined, though. The close relationship that existed between Doug and Frank throughout the series' run made the revelation all the more jaw-dropping.
The truth was eventually exposed in the final season, as House of Cards ultimately revealed that Doug gave his one-time mentor an overdose of the latter's liver medication. Thus, no more Frank Underwood.
Since one good shock deserves other, the murderer ended up becoming a murder victim himself when the shifty Claire fatally stabbed Doug in the Oval Office, using a letter opener. That scene was the final one filmed for House of Cards, and was directed by Michael Kelly's screen partner and the series' star and rescuer, Robin Wright. Kelly shared what it was like filming the climatic conclusion, saying this to EW:
It is safe to say that Michael Kelly underwent quite the emotional rollercoaster. He goes from shooting an emotionally draining death scene for an extended period of time to then saying goodbye to the cast and crew he has come to care about deeply. Speaking of that crew, House of Cards aficionados know too well about the show's near-premature end. In his interview, Kelly joins his fellow co-stars in crediting Robin Wright with saving the series.
Some fans may be wondering what on earth Doug was thinking when he went to see Claire. More specifically, was he was prepared to die? Michael Kelly provided insight into Doug Stamper's mindset, saying:
As it turns out, Doug's play turns out to be his last. Instead of getting his pardon, he got killed. Earlier in the interview, Michael Kelly said that he believes Doug finally found peace in his final moments. Citing Doug's inability to kill Claire caused by him still seeing "a part of Frank there."
So, what was Doug thinking amidst his ultimately lethal confrontation with Claire? Michael Kelly shared that Frank's one-time right-hand man feels as though that's the way it has to be. In the end, Doug made it to the final episode of the series, but since he did not survive his final scene, you can probably count out that Doug Stamper spinoff. Unless they made it a prequel...
