What looked like a bad accident or an art installation was actually part of the set of a new film being shot in SF.
The movie, "Dawn of the Planet of the Apes," is about a group of scientists in San Francisco who try to survive in the aftermath of a deadly plague.
It's the sequel of "Rise of the Planet of the Apes," which was also shot in San Francisco and Muir Woods.
The upcoming film stars Andy Serkis, Jason Clarke, and Keri Russell.
It opens in theaters next July.
