If anything can attest to the popularity of Netflix drama House of Cards, it's the fact that a 25-second teaser can incite extreme excitement in even the most casual of TV viewer.

Now with season four just over a month away, we've been treated to our first official teaser for the approaching series.

The brief clip shows Doug Stamper (Michael Kelly) - the president's long-suffering and (spoilers if you haven't seen the season three finale) now-murderous aide - digging a grave alongside Kevin Spacey's Frank Underwood.

This being House of Cards, there is, of course, a slight twist to what you're watching; watch the clip below to find out.

There are no signs of any other characters from the series, most notably the First Lady, Claire Underwood (Robin Wright).

There has also been no word on what to expect from the new season plot-wise but, going by the first three, we're going to go ahead and assume there will be plenty of machiavellian scheming, lots of head-locking and a dose of murder.

The fourth season of House of Cards will be available to watch on Netflix from 4 March.
