Box Office Underperformance: When "One Direction: This Is Us" was released, it was predicted that the film would gross over $20 million dollars in its first three days. With "Getaway"'s scathing reviews and "Closed Circuit"'s limited release, it was all but certain that "This Is Us" would be the highest grossing new release of the week. Reining champ "The Butler," while still poised for a strong weekend, was headed for about $12 million dollars, a sizable margin behind the 1D film. After the first day, "One Direction" grossed $8 million and expectations were slightly lowered. However, it was still the favorite to win the crown that weekend. Things changed when "This Is Us" dropped a huge 54% from its second day. Now, it was looking that 1D would very narrowly squeak out a win for the weekend. Additionally, the four-day Labor Day weekend, which "This Is Us" was expected to win, seemed to be headed in one direction: to "The Butler." In the end, it barely cracked $15 million and while edging out "The Butler" for the three-day weekend, had to settle for second place in the four-day frame.
Colbert Bump: The One Direction fan base are strong enough to make new artists' careers (i.e., Ed Sheeran, 5 Seconds of Summer), derail rising artists (The Wanted) and bring once-mighty stars to their knees (Justin Bieber).
Creator Killer: Nothing has yet happened to 1D themselves, but they are one of, if not the main catalyst in the declining popularity of Justin Bieber (although Bieber's increasing Jerkass behavior that started around the time 1D became popular may have also had something to do with it).
You wouldn't know Niall was Irish if you only ever heard him speak in his American accent.
Louis pulls off a fairly good (if extraordinarily hammy) American accent, too.
Fake Brit: Niall, the same as above. They all swapped accents in one video diary, and Niall's imitation of Louis's Yorkshire accent was pretty hilarious.
Fake Irish: While Niall is actually Irish and just good at accents, Harry (who likes to imitate Niall's accent, especially when the band is actually in Ireland) is not.
Name's the Same: They were sued by a little-known band who registered the name after their creation but before they came to the US. The U.S. One Direction were renamed Unchartered Shores and their careers were destroyed by the lawsuit.
