One Direction and VEVO debuted the music video for Best Song Ever on Monday, showing the United Kingdom band prepare for a film role and causing chaos.

"And we dance all night to the best song ever," the band sings in the chorus. "We knew every line/now I can't remember/how it goes but I know/that I won't forget her/'Cause we danced all night to the best song ever."

In the music video, Niall Horan, Zayn Malik, Louis Tomlinson, Harry Styles and Liam Payne met with studio executives to discuss their upcoming film documentary This Is Us. The footage also premieres snippets from the movie, which hits theaters in August. Each band member also dresses up to portray a different character either than themselves. Horan becomes a bearded studio executive and Styles becomes a nerdy "marketing guy." Payne acts as Leroy the choreographer, sporting a blonde wig that forces all the singers to open their mouth in shock.

Best Song Ever is featured on the soundtrack to their film This Is Us, which will be released in U.S. theaters on Aug. 30.

"Maybe it's the way she walked," Styles opens the track singing. "Straight into my heart and stole it/Through the doors and past the guards/Just like she already owned it."

The band also displays a ton of dance moves in the music video, though they admitted to the August 2013 issue of Glamour magazine that they do not dance. They admitted that they do not dance both because they cannot and will not.

"We look stupid dancing. That's what I think," Payne said. "We just kind of came out and said, "We can't dance. We're a bit lazy. We're just normal lads."
