This is why Taylor Swift was credited in Lena Dunham’s ’Sharp Stick’ movie

Lena Dunham revealed why she gave Taylor Swift a credit in her new movie, Sharp Stick.

Appearing on IMDb’s “5 Burning Segments” bit, Lena said she thanked both the “Shake It Off” singer and her boyfriend, Joe Alwyn, in the movie’s credits because of their involvement in the project. Although they didn’t make a cameo, the actress said they provided some help behind-the-scenes.

“They are just really great friends of mine who watched a really early cut of the film and gave me notes. They’re both just really interesting, perceptive people,” the Girls star explained. “Taylor’s been one of my close friends for a really long time and Joe is an actor who I actually ended up working with on a project that I shot just a few months after this.”

Continued Lena, “To have those smart people who are titans of industry in their own way look at the story and give me honest and generous feedback? That’s all you could ever hope for.”

Sharp Stick premiered January 22 at the Sundance Film Festival. The movie stars Lena, Kristine Froseth, Jon Bernthal, and Taylour Paige.
