11 Signs that One Direction's Movie Will Be a Hit

Morgan Spurlock's One Direction documentary, This Is Us, will likely be a smash. Not only does it star the most popular boy band in the world — made up by Zayn Malik, Harry Styles, Niall Horan, Louis Tomlinson, and Liam Payne — but the trailer is backed by a new single, "Best Song Ever," which is about as subliminal as Styles is clothed.

How else do we know This Is Us is guaranteed to be a greater hit than, say, the disappointing Jonas Brothers: The 3D Concert Experience? Let us count the ways:

Shirtless Harry.

Anonymous shirtless 1D.

Pant-less Harry.

Shirtless Louis.

Rampant homoeroticism.

The Fans. Oh, the fans.

"I know they love me, even [though] they don't know me."

Also, clearly, Simon Cowell has given up his riches in order guarantee One Direction's success, and now works reception in a spa.

Bonus: One once took a picture in a grave, which means... secret vampire?
