Cast members of Broadway’s “Phantom of the Opera” were “devastated” Saturday to learn that a longtime dancer on the show, Harlan Bengel, 45, had committed suicide the previous day by hanging himself from the Winterdale Arch in Central Park.

“Absolutely devastated — a sad environment backstage today, but all I can do is do my duty and perform to honor his legacy,” one cast member, who asked not to be named, said before the night’s performance.

“He always said ‘Hi’ to me and did his job. Makes you think about life,” another cast member said of the quiet, troubled actor.

Harlan, who also had roles in the Broadway hit “War Horse,” was discovered dangling from the overpass, near Central Park West and W. 82nd St., at daybreak on Friday.

Eerily, three years ago, Bengel had posted a YouTube clip from Les Miz of the character Javert singing of suicide and flinging himself off a bridge, commenting, “No! NOOOOO0!”

Harlan’s current Facebook profile photo also showed him standing on a bridge.
