So, your kids, nieces, grandchildren or next-door neighbors’ daughters are obsessed with One Direction, but you can’t tell Harry or Liam from Ringo. (Just kidding. There is no Ringo. That’s a different band, with an equally passionate fan base.) Don’t worry, non-Directioners. We’ve got you covered with some key information that can help you brush up before the pop group’s 3D biographical This Is Us roars into theaters on August 30. 

Obviously, there is far too much trivia out there on the band for us to cover on one page. Thankfully, One Direction has one or two fan sites you can surf. For our purposes, let’s start with the band’s origin, because they started as five individual singers who auditioned for Britain’s televised talent show The X Factor in 2010. 
 

 
Individually, Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson couldn’t make it to the final rounds. But Executive Producer Simon Cowell saw something special in these five singers, and he took a gamble. He put them together as one band, and One Direction was born.
 

 
They didn’t win the finals, but the band was off and running. And while most of this is covered in the new One Direction movie, it’s important to know that these guys were regular X Factor contestants who simply managed to make a HUGE impact on England and – later – the world. 
 

 
Don’t feel too bad for the boys. They made a triumphant return to the X Factor stage in 2012 to perform their massive tune “Kiss You.” 
 

 
“Kiss You” is just one of many One Direction songs to make it to the top of the U.K. and U.S. billboard charts – and you’ll hear a mix of every hit single in This Is Us, which mixes concert footage with behind-the-scenes antics from the five “mates” (who all seem to be very close friends in real life). 
 
Have you heard these songs once or twice before? 
 
"What Makes You Beautiful"
 

 
"One Thing"
 

 
"Up All Night"
 

 
"Live While We’re Young"
 

 
But the band maintains its popularity because preteen girls adore them – obviously – but also buy into their self-deprecating senses of humor:
 

 
And it’s worth noting that the boys recorded an original song for the movie, which likely will be featured on their next album, Where We Are. Memorize the lyrics to “Best Song Ever” and you’ll really impress the young ones you end up bringing to the theater for the 3D One Direction (or 1D) movie!
