Police in Ohio have arrested a man who allegedly tried to smuggle guns, ammunition and knives into a late-night showing of "Dark Knight Rises."
Authorities say ... the manager of the Cleveland-area movie theater became suspicious of the man, who allegedly tried to bring a satchel into a 10pm Saturday showing of the Batman movie.
The manager reportedly alerted an off-duty cop who was working security that night ... who searched the bag -- found a Glock 9mm handgun, ammunition clips, and three knives -- and immediately alerted police.
Cops say the man, identified as 37-year-old Scott Smith, does NOT have a permit to carry a concealed weapon.
According to reports, the man was arrested without incident ... and even offered to put the guns back into his car. Obviously, that didn't happen.
Cops later performed a search of Smith's home. It's unclear if investigators discovered anything during the sweep.
