Did you ever want to run away and join the circus? I never did–it seemed to me that performing in a circus was hard work, and without any particular talent useful to a circus, one would end up doing even harder, dirtier work. For those of us fascinated with circus life but lacking the courage to sign up, PBS offers Circus on Blu-Ray and DVD. This six-hour mini-series premiered on PBS November 3 and will be available for purchase November 9. From its beautifully filmed opening credits throughout scenes of a show being mounted, Circus introduces viewers to a world few have seen.
