Anthony Cureton of the Bergen County Sheriff's Office said the threat proved unfounded.
Some moviegoers said a bit of panic was caused by some type of noise -- possibly caused by someone falling during the evacuation between 9 and 9:30 p.m.
The sheriff's Bomb Squad responded along with borough and Fairview police. A sheriff's K-9 search the building with negative results.
"In the ['H]unger [G]ames['] movie, there was a thud from the top of the theater. Everyone turned around to see someone climbing over the top row of seats," @CaseyBella__ said in a Twitter message. "Some other commotion caused mass panic in the theater and everyone evacuated, screaming and running."
