house of lies*It might be a smart move for Hollywood executives to stick with movie sets and green screens instead of choosing the real thing (you know, for safety reasons).

TMZ reports that rival gangs exchanged gunfire during production for the popular Showtime drama “House of Lies“…forcing a location change.

The cast and crew—including actor Don Cheadle, rapper T.I., and actress Kristen Bell—rolled the dice and gathered outside the Nickerson Gardens housing project in South L.A., despite its notorious history of gang violence.

As the crowd of onlookers began to swell, gunfire erupted, sources say.

TMZ’s initial report doesn’t reveal the number of cast members present during the shooting, but sources confirm there were no injuries.

When local authorities finally arrived on the scene, both gangs were already long gone.
