In the beginning, after the chandelier is brought out, there are brief glimpses of some golden statues that have exposed breasts.

A woman changes costumes onstage. No nudity seen as she is behind a screen.

Many kisses. Some prolonged, but none very heavy/passionate.

Some dresses are low-cut.

"Music of the Night" song and choreography could be seen as suggestive, but nothing explicit. Various sex references in some songs, most not very noticeable. Example: "...Who'd believe the diva's happy to relieve a chorus girl who's gone and slept with the patron. Raoul and the soubrette entwined in love's duet. Although he may demur he must have been with her..."-Notes/Prima Donna

Most explicit episode is "Point of No Return" lyrics and choreography. Some camera close-ups of man's hands running across woman's body (fully clothed).

The disfigured Phantom's revealed face is severely disfigured.

D-word several times. The Phantom curses Christine for removing his mask. One character nearly uses the s-word but replaces it with the word "gibberish"

Several times the chandelier showers sparks. Each one is loud and unexpected

The Last Scene: Down Once More/The Final Lair/Point of No Return Reprise (Many names for it.) is the most intense scene. Character threatened with hanging.

Some descriptions, appearances of Phantom are eerie and threatening. Characters scream when they realize the "ghost" of the opera house is near.

The Phantom's despair and anger over being betrayed may upset some viewers.
