The first track on Taylor Swift’s “The Tortured Poets Department” is called “Fortnight,” and it features a collaboration with Post Malone.

The music video for the song also features Baltimore’s Josh Charles, an actor known for his television roles in “We Own This City” and “The Good Wife,” and in the movies “Hairspray” and “Dead Poets Society.”

Swift invited Charles, who played Knox Overstreet in the 1989 hit “Dead Poets Society,” to be a part of the video. Swift referred to Charles and co-star Ethan Hawke as “colleagues from down the hall” (tortured poets, meet dead poets).

Charles called Swift “genuine” and a “kick-ass director.”

“I’ve admired Taylor for a long time, but meeting her in person took my fandom to a whole new level,” Charles wrote on social media.

On Instagram, Charles wrote that it was hard for him to keep his role in the music video a secret and that he hadn’t even told his children until just a few days before the album was released. He said Swift and her crew were excellent to work with.

“What I’ll remember most was the laughter. There was a lot of it. Like we were 17 all over again,” Charles wrote on Instagram.
