The Italian art-house film Caesar Must Die and the teen zombie-comedy Warm Bodies do not, at first glance, appear to have much in common. But they share a bit of creative DNA, both being inventive riffs that turn Shakespearean tragedies into something else entirely.

While many Americans will be tuning into the Super Bowl on Sunday, there's another big sports competition this weekend: the Cyclo-Cross World Championships. This weekend's event, in Louisville, Ky., marks the first time in its 60-year history that the world championships will be held outside of Europe.

Cyclo-cross, a grueling sport requiring riders to traverse mud, sand and other obstacles, is growing rapidly in the U.S. And the fans can be a bit crazy. At the 2012 Louisville Derby City Cup, hundreds of people — some in costumes — packed onto the course to cheer the riders on.

As cocaine consumption falls in the United States, South American drug traffickers have begun to pioneer a new soft target for their product: big and increasingly affluent Brazil.

And the source of the cocaine is increasingly Bolivia, a landlocked country that shares a 2,100-mile border with Brazil.

As Brazilian police officers and border agents can attest, the drug often finds its way to Brazil by crossing the Mamore River, which separates the state of Rondonia from Bolivia in the heart of South America.

Dave Grohl has always been a joy to watch onscreen, whether bashing away at a drum kit like the heavy-footed, wild-haired spawn of John Bonham and the Muppets' Animal in Nirvana's "Smells Like Teen Spirit" video, or flashing an endearingly goofy grin in the Mentos-spoof clip for the Foo Fighters' "Big Me." And a big part of that appeal is the sense that no matter how long he's been in the business, Grohl is still a guy who is acutely aware that he's living out a teenage daydream every day of his life.
