The three 18-year-olds, friends since middle school, are about to go off separately to college this fall. But on Sunday, these avid fans of the Batman film franchise had no doubt where they wanted to be: Together, at the movies, watching The Dark Knight Rises.

"What happened in Colorado was horrible, but that guy was just a psycho," said Sahil Agrawal, of Queens in New York City, waiting with friends David Kim and Danny Wong for an Imax showing on Manhattan's Upper West Side. "This wasn't going to change our plans."

The three were typical of hordes of fans who packed theatres across the United States over the weekend, keeping plans to see the final installment of the phenomenally successful Batman trilogy despite Friday's horrific shooting in Colorado. Despite the occasional jitter — reflected in the choice of a back-row seat, perhaps, or a glance to see what security was in place — the fans seemed determined to look beyond the shooting.

'I'll be honest, I'm kind of scared.' —Moviegoer Jen Jackson

"I'm not going to let some nut who shoots people dictate what I'm going to do," said Ron Bondy, 36, in Bismarck, N.D., a sentiment echoed by fans all over the country.

Not that there weren't some evident qualms among moviegoers. At the same theatre in Bismarck, Jen Jackson had insisted upon one thing to her husband: They were going to sit in the back row in case they needed to get out fast. The 29-year-old architect was also forgoing the popcorn — not as a precaution, but because nerves had stolen her appetite.

"I'll be honest, I'm kind of scared," said Jackson. She had hesitated to come at all. But her husband, Patrick, standing alongside her, was pragmatic: "I don't think anything would happen in Bismarck."

Warner Bros. and other studios banded together to withhold the usual weekend revenue reports until Monday, a day later than usual, out of respect for the victims. But industry estimates suggested the film was on track to be the third highest opening weekend ever, after The Avengers and Harry Potter and the Deathly Hallows — Part 2.

'Movies are about coming together'

Katie Birkel had no intention of missing the occasion. She was at a Manhattan showing along with three friends, celebrating one of their birthdays. Birkel said she had been inspired by a statement from the film's director, Christopher Nolan, after the tragedy, which occurred at the midnight showing in Aurora, Colo.

"He said that movies are about coming together and sharing an experience," noted Birkel, 28. "I agree with that."

Mike Sumner, standing a few steps behind her in a Batman T-shirt, said he was comforted by seeing the NYPD outside the theatre — at least two officers were patrolling outside. "Colorado was an isolated incident," he said. "I'm not afraid of copycats. Besides, I'm a New Yorker. We're always vigilant."

Police were also visible outside a theatre in McAllen, Texas, near the Mexico border, where an officer firmly waved away drivers who attempted to stop in front.

Inside, Juan Carlos Rivera waited with his mother-in-law and his wife. The 38-year-old Brownsville resident said the family had been big fans of the first two movies and wouldn't want to skip the third.

"It looks like it was an isolated incident," Rivera said of the mass shooting. He said he'd probably sit on the aisle — not out of fear, but because his wife was pregnant and might need the restroom. "You can't allow a random event like that to terrorize you," he said.

Besides, many said in interviews, what was the chance that lightning would strike twice?

"I don't think that that many people are crazy enough," reasoned Dayna Freeman of Kansas City, Mo.
