Casper Christensen

In Klovn, Casper Christensen plays a version of himself: charming, shameless, and endlessly pleased with his own cleverness. He is Frank's best friend and creative partner, forever dragging him into schemes that promise fun and reliably end in disaster. He seduces easily, lies fluently, and never once doubts he is the reasonable one.

The joke is that he built this show and cast himself as the guy who is almost always right, even when he is obviously terrible — a bit of vanity the series turns into its sharpest running gag. Christensen commits to his own awfulness with total ease, and that fearlessness, the willingness to be the joke, is what makes him so purely fun to watch.
