Cage-rattling Chinese artist Ai Weiwei lives in a Beijing complex with his wife and some 40 cats and dogs. Only one of the animals — a cat — has figured out how to open the door to the outside. This ready-made metaphor arrives early in Alison Klayman's documentary Ai Weiwei: Never Sorry and is never mentioned again. But it underlies the tale of one of the few contemporary Chinese who publicly defies the government.

In 1968, two music producers went to a Detroit dive called The Sewer to hear a Mexican-American protest singer with a small cult following.

The producers' client list was mostly Motown, but they immediately signed Rodriguez (full name Sixto Rodriguez), whose stirring lyrics they hoped would speak to disenfranchised outsiders of all stripes and their champions.

The savings are never passed on to the consumer, but a little product placement has become standard practice for Hollywood movies — a pizza box here or a conspicuously angled soda can there, and few take notice. But product integration is another matter: If a movie has been explicitly designed to accommodate a sponsor, it's worse than just a commercial movie. It's a movie commercial.

Rebeca Espinal admits with a shy smile that she's a straight-A math student. She's a high school graduate who dreamed of going to college.

"I was planning on getting a degree in international relations, but with financial aid and how difficult it is to pay for college and everything," she says. "So when Siemens came along and gave me the offer, it was too good of an opportunity to just let it go.

The province of KwaZulu-Natal has emerged as the epicenter of South Africa's HIV epidemic. South Africa already has more people infected with HIV than any other country in the world, but parts of KwaZulu-Natal have HIV rates that are more than twice the national average.

Now in addition to HIV and AIDS, the province is also dealing with a major tuberculosis epidemic.

In the northeastern part of KwaZulu-Natal, dusty dirt tracks wind through pastures and fields of sugar cane. The hillsides are dotted with small huts made of cinder blocks and field stones.
