[The sets are big: The apartment houses lining the Manhattan street set stand between 46 and 48 feet tall. They're so tall that the lights couldn't be hung with conventional Genie lifts that reach 40 feet. Instead, a track had to be hung from the ceiling grid, 58 feet up.] We fly a man up to the track, ... and there's a little seat and he can push himself along the track and focus the lights.
— James Noone
