Sgt. John McLoughlin, the Port Authority police officer whose tale the film recounts, strolled into the Ziegfeld Theatre in New York with big screen counterpart, Nicolas Cage, the New York Post reported Friday.
"I think he did a wonderful job," said McLoughlin, who was trapped 30 feet under a pile of rubble when the twin towers collapsed.
Cage also called McLoughlin a "true hero," adding that he does not think that it's too early to show a film depicting what is now known as America's darkest day.
"The spirit in which it was made is one of solidarity and respect," he said.
"I think it's very powerful," said Scoppetta.
