Smith, 38, of North Ridgeville, Ohio, was arrested in August 2012 after an off-duty police officer saw him enter a Westlake theater with a bag containing a 9-millimeter Glock semi-automatic pistol and four knives.
He pleaded guilty to concealed weapons charges, but fought and was acquitted of a charge of having a weapon while under disability, The (Cleveland) Plain Dealer reported.
His arrest, at a showing of the Batman-themed film "The Dark Knight Rises," came two weeks after a gunman entered an Aurora, Colo., theater, showing the same film, and killed 12 people, wounding 70 others, the newspaper noted.
In sentencing, Cuyahoga County Common Pleas Court Judge Kathleen Ann Sutula said she had to send a message to the public that Smith's behavior could not be permitted.
