Seen from the performers’ point of view, Circus World is a wonderfully human look at the tensions and harmony of families living in a circus environment, complete with The Flying Gaonas, exhilarating highwire acts, clowns, and the amazing feats of Gunther Gebel-Williams, the famous wild-animal trainer. "Circus World" was shown exclusively at the 600-seat IMAX theater at the Circus World theme park in Central Florida.
