Last night's Veep was a format-breaking episode presented as the long-gestating documentary Selina's daughter Catherine had been filming all season. It not only detailed the results of the electoral tie-breaker vote in the House of Representatives, but cast new light on a lot of events we had witnessed earlier in the season. I spoke with Veep showrunner David Mandel about how and why they pulled off the documentary episode, coming up just as soon as I make a call from an elementary school classroom... You set up Catherine doing the documentary early in the season. Did you know then that it would become the frame for a whole episode? David Mandel: Yeah. It's a little chicken and the egg, in terms of which part came first. I think I was partially inspired by some of the episodes like the testimony episode, and the interview episode they've done in the past.
