Explosion on 'Matrix 4' set causes damage to street in San Francisco

The Matrix 4 is currently in the throes of filming some pretty involved action sequences in San Francisco, with one scene last night involving an explosion which damaged nearby street furniture.

According to NBC, plastic coverings for nearby advertising hoardings and street lamps melted after the controlled fireball went up.

“We just saw the plastic that was all melted, so we didn't know what was going on,” Encar Orozco, an employee of JCDecaux told the channel, after finding $2000 worth of damage had been done.

“We called our manager and we found out that it was some explosion for the movie.”

Passersby near the set have managed to film some of the explosions taking place, as helicopters circle overhead (via Reddit).

Others, meanwhile, have spotted what appears to be another scene featuring dozens of black suited agents giving chase.

Then last week, another elaborate set piece saw two black-clad stunt performers leaping off a skyscraper while attached to wires.

The long-awaited sequel seems to be running at full pelt, with Lana Wachowski once again behind the camera.

Keanu Reeves is reprising his role as freedom fighter Neo, with Carrie-Anne Moss back as Trinity and Jada Pinkett Smith as Niobe.
