One Direction Get Wacky In 'Best Song Ever': Watch Now!

1D meets their alter egos in the Ben Winston-directed clip.

One Direction are heading off to Hollywood for their very comical "Best Song Ever" video, which was released Monday (July 22). The visual follows the story of the boy band as they meet with various La La Land bigwigs, who are trying to make the superstars even more famous in a pitch meeting for their August 30 movie release, "This Is Us."

And, yes, if you look closely, the five moguls in the clip are actually the guys of 1D cleverly disguised as the various movers and shakers one might meet out in the City of Angels.

There's two studio executives who are in varying degrees of going bald, Harvey (Niall Horan) and Johnny (Louis Tomlinson); a bespectacled, marketing guy named Marcel (Harry Styles); a headband-loving choreographer, Leeroy (Liam Payne); and Veronica, a sexy female assistant (Zayn Malik, who had perhaps the most stunning of the makeovers).

The meeting with studio execs about "the greatest movie of all time" leaves the guys rejecting all the ideas for their new image: uniform boy band costumes, all-purple Justin Bieber-inspired costumes and lots of sculpted abs. They guys get fed up and run amok around the office, trashing things and breaking out into a big dance number.

The Ben Winston-directed video is full of wacky moments, including all the guys dancing next to their alter-egos. Harry flirts with Z's femme fatale while Liam's choreographer character deals out kisses. In between the comic elements of the visual, fans are also treated to some footage from "This Is Us."

The video was shot on June 12 and 13 in Miami. Not only does it serve as the lead single for their movie release, but also for their third album release, rumored to be hitting retailers this holiday season.
