Huntsville Police spokesman Harry Hobbs said the department has contingency plans in place for any issues that may arise. He also said several theaters have hired off-duty police officers for the movie showings.
A gunman opened fire at the midnight premier of the latest movie in the Batman franchise in an Aurora, Colorado theater, killing 12 people and injuring dozens more. Nine of the injured are reportedly in critical condition.
Authorities have James Holmes, the suspected lone gunman, in custody. Police reported booby traps and explosive devices set at his home.
No shows have been canceled and ticket sales do not seem to be impacted.
Representatives at Monaco Pictures in Huntsville said its policy is to not allow guests wearing costumes that have masks.
"We probably had a dozen people show up that had masks and ask them to remove it and they're okay with that," said Vice President of Operations David Bier.
"It's normal getting into the spirit of the film and you want to dress up, but really out of respect and safety, you need to make sure you can see the guest's face and let us do our jobs," he said.
Bier said the theater will also have an extra officer on-hand during the film's opening weekend.
