We should probably point out off the top that The Thick of It, the terrific British political satire created by Armando Iannucci -- the mind behind the new HBO comedy Veep -- is not technically cancelled. (It's definitely brilliant, though.) Since airing its first two series of three episodes apiece back in 2005, The Thick of It has returned to the BBC for a series of specials that aired in 2007 and an expanded eight-episode third series which ran in 2009. (BBC America aired the first two seasons stateside in 2006 and will start running the third season on April 28.) Additionally, a fourth season is currently being filmed and will air in the U.K. sometime in the fall.
