Two gay men kiss.

There are some scenes in which the characters become trapped in the World Trade Center.

(Not actual footage) A female character observes a man jump out of his office in the World Trade Center.

Individuals attempt to escape via staircase but the camera violently shakes implying that the building is collapsing.

People are bleeding (usually from their heads).

A couple mild obscenities, plus one of the S-word and the F-word each.

Several of the character's friends/family members perish (some are implied being killed while talking on the phone then the line gets cut off).

Some actual footage of the twin towers burning or collapsing are shown.

Characters witness the aftermath in shock and cry as they watch the mushroom dust clouds rise from where the twin towers were (animated).
