There’s something inherently photogenic about the circus, especially the unsung, small family operations that cross the countryside.

The film “Circo” has even more going for it, since it occurs across the landscape of Mexico. There, filmmaker Aaron Schock follows the Gran Circo Mexico, trying to keep the traditions alive by pulling their rickety trucks and exotic animals into the smallest villages, erecting tents and rounding up locals to see their acts.

Children are raised to learn an acrobatic skill, and the troubles of the circus take their toll on relationships. Despite the hardship, the modest circus is photographed so evocatively, it will still make you want to run away with it.
