Another film set in a circus,f ilmed in CinemaScope is Trapeze (1956)

For those that admire this film just for the sheer spectacle of seeing a very early CinemaScope film, phtoographed in a circus. I recommend Carol Reed's film Trapeze (1956) http://www.imdb.com/title/tt0049875/ which over all is a better film, but still features some equally great CinemaScope cinematography. Including the camera suspended from the ceiling of the big top tent, as the trapeze artists swing across the width of the screen!
