Drew Carey's Improv-A-Ganza is a WLIIA? spin-off that aired during the spring and summer of 2011 on the cable network GSN (Game Show Network). Much like the short-lived Drew Carey's Green Screen Show (2004-2005), it was hosted by Drew Carey (who had since improved his Improv skills), and featured all of the US main cast as well as recurring stars Greg Proops, Brad Sherwood, Chip Esten and Jeff Davis.
The show also featured guest appearances by celebs such as Charlie Sheen (who co-starred with Ryan Stiles in the Hot Shots! parody films and CBS sitcom Two and a Half Men) and Kathy Kinney (who played Mimi on The Drew Carey Show), and introduced other improv talent like Heather Anne Campbell and reintroduced Sean Masterson from Drew Carey's Green Screen Show and Jonathan Mangum, who had also been on Green Screen Show as well as the non-broadcast Whose Live? shows with the WLIIA? crew for years in Las Vegas and then later joined the 2013 reboot of the US show version.
The show had all of its episodes broadcast online both the network's official site and its YouTube channel but, despite critical praise and heavy promotion, was cancelled due to low ratings.
