Sweet! I'm an improv actor in Calgary, Alberta, and have always loved improv with this sort of context. Last year I saw the excellent Toronto production of "Battleawesome Awesomestar", which draws a pretty obvious inspiration. Can't make it to Chicago, but I'll cheer from here!
Inceidentally, my group will be mounting a show this year at the Calgary Comic & Entertainment Expo which will pit Star Trek characters against Star Wars characters in what is essentailly an improv hockey game. Canadian geek chic at its best, eh?
