WATCH: Taylor Swift is sharing behind-the-scenes footage of her time on set with Post Malone while filming their ‘Fortnight’ music video.

Taylor Swift is showing fans another side of her creative process with new never-before-seen footage from the set of her “Fortnight” music video. The featurette shows Swift in directorial mode, explaining shots and coming up with Easter eggs on the fly.

The video opens on a stunt gone awry, when Swift attempts to hurl a wheeled cart through a mirror. Instead of shattering the glass, the cart ricochets backwards as Swift becomes visibly startled and then breaks down laughing.

“This is basically in my mind taking place in ‘The Tortured Poets Department’ which is a government municipal building where they study the behaviors and minds of poets,” she explains. “One of the stereotypical things about poets over the years is that people said they were crazy.”
“Fortnight” featuring Post Malone is the first single off of Swift’s 11th studio album, titled The Tortured Poets Department. The music video shows Swift as both institutionalized and as an employee of the department alongside Malone. At one point in their relationship, the duo works face to face on typewriters.

In the new behind-the-scenes footage, the “Sunflower” singer appears blown away as he learns how to use a typewriter for the shoot. “All you do is move it? This is amazing,” he gushes as Swift shows him how to work the machine. “I feel very steampunk.” Swift replies, “We don’t see working typewriters! Millennials don’t see that s**t.”
