I first became aware of "Whose Line is it Anyway?" through the reruns of the original British version on Comedy Central. Though Clive Anderson (the original host) was not as funny as Drew Carey, he had a knack for delivering witty barbs and insults. Then, in 1998, the show came to America (apparently, we wanted it and bought it). Clive Anderson came with it, but after a handful of episodes, he was replaced with Drew Carey. I guess the stuffed suits in the studio thought that American audiences would relate better to an American host.
Most episodes of the American "Whose Line" star Wayne Brady, Colin Mochrie, Ryan Stiles, and Drew Carey, with a fourth actor rotating in and out. These usually consisted of Greg Proops (a frequent guest on the British 'Whose Line'), Chip Esten (also occasionally on the British), Brad Sherwood (also seen in UK), Kathy Greenwood, and Denny Siegel, though there were also appearances by Ian Gomez (Larry Almada on 'The Drew Carey Show'), Steven Colbert (yes, THE Steven Colbert!), Kathy Kinney (Mimi on 'The Drew Carey Show'. You can see her here without makeup!), and my all-time favorite, Josie Lawrence, a frequent participant in the British 'Whose Line', whose comic genius and musical abilities made an excellent complement to Wayne's on the American. Though many women have appeared on "Whose Line" since it first debuted in the UK, Josie, IMHO, is the "Whose Line Diva".
The cast participates in various improv games, and improved songs, most of which set the audience roaring in laughter (and me too!), especially in one of the most popular games, "Hoedown", one of the remnants from the UK's version. I have every intention of adding both versions of this release to my collection, and intend to purchase every "Whose Line" DVD release, which hopefully will be frequent. :) And not just the American, but let's get the British "Whose Line" over here too! Comedy Central has stopped airing them to make room for "Mad TV" and "The Daily Show", which are not my taste.
