Harry Styles Crashes Sundance Premiere Of New Zach Braff Movie

The One Direction member brought boy band madness to Park City.

Park City, UT — In recent years, Sundance has become one of the biggest parties in the movie industry with swag suites and paparazzi growing in number with each fest. But never has the independent film festival experienced the hysteria that can come to Park City once a member of One Direction shows up.

Harry Styles was sighted around the Sundance Film Festival on Saturday (January 18), apparently there to support the premiere of "Wish I Was Here," the new film by Zach Braff. Styles walked the red carpet and posed for photos with Braff and the writer-director's best bud and co-star, Donald Faison.

Styles and Braff were also joined by Donald Faison. The former "Scrubs" stars are famous for their off-screen friendship, so we can't really blame Styles for wanting to join in on the fun.

And now a silly one!
