We know Robert Hanna because of printing his black and white still photographs of circus life. It turns out Hanna is actually a specialist in moving images--and he is one of two principal cinematographers on the documentary series "Circus", a multi-part documentary series premiering November 3, 2010, 9:00pm-11:00pm on PBS.

A gallery of Hanna's intimate stills from the series is on PBS's website here. His photography gives a behind-the-scenes glimpse of what happens to the performers beyond the performances.

From the PBS website: "[T]he documentary follows the legendary Big Apple Circus on an unforgettable journey from the big top to the “back lot,” where nail-biting drama unfolds both high in the air and down on the ground and the real heart of the circus beats. CIRCUS goes behind the scenes to explore a distinctive world with its own rules and lingo and no fixed address."
