Over the course of one Broadway musical season (2003-2004), "ShowBusiness" follows the four high-profile productions that would eventually become Tony nominees for Best Musical: a big-noise musical named "Wicked," the Rosie O'Donnell/Boy George collaboration, "Taboo," the much-anticipated Tony Kushner musical, "Caroline, or Change," and an irreverent puppet show named "Avenue Q."

From casting to staging, from previews to red-carpeted opening nights, from the announcement of Tony nominations to the suspense-filled Tony Awards, "ShowBusiness" provides a never-before-seen look at the inner workings of Broadway musicals. Allowed unprecedented backstage access, director Dori Berinstein casts a camera's eye on rehearsals, backstage highs and lows, and the mysterious and wondrous creative process.

Featuring a star-studded array of Broadway icons as well as ambitious new faces, "ShowBusiness" proves that 2003-2004 was truly a season to remember.
