Regal Cinemas has started checking movie-goers' bags in the wake of two separate theater attacks this summer.
A gunman killed two people and himself in July, during a showing of "Train Wreck" in Lafayette, Louisiana.
A week later, a man attacked people in a Nashville theater with a hatchet and pepper spray.
The move from the nation's largest movie theater chain comes as many are debating safety measures, such as metal detectors and armed guards at theaters.
