Veep has emerged as one of HBO's most popular series, with Seinfeld star Dreyfus playing the confident but ultimately clueless vice president of the United States of America. The actress won an Emmy award for the role last year.

Dreyfus hit the headlines last week after she appeared on the cover of Rolling Stone with a flawed tattoo of the Constitution on her back. It erroneously featured John Hancock's signature - from the Declaration of Independence. 

Last week, Veep returned for a third season with 955,000 viewers, which was down 20% from the 1.2 million who tuned into the show's second season, but still enough to persuade the head honchos at HBO to renew.

Veep is created by Armando Iannucci - the man behind Alan Partridge, In The Loop and The Thick of It. 

Silicon Valley is partially inspired by Mike Judge's own experiences as a Silicon Valley engineer in the late 1980s. Cast regulars include Thomas Middleditch, T.J Miller, Zach Woods, Kumail Nanjiani, Martin Starr, Josh Brener, Amanda Crew and the later Christopher Evan Welch. 

It pulled in 1.6 million viewers on Sunday (April 20, 2014) after the previous Sunday's premiere pulled in 2 million viewers.
