Producer Ben Winston (pictured left) has confessed that One Direction's fast-moving success can be attributed to their use of social media.

He worked on the lads' new movie 'This Is Us' and explained to The Hollywood Reporter that the way they have utilised outlets such as Facebook, YouTube and Twitter has helped them to reach international levels of fame in a very short period of time:

"Social media has helped them almost skip the queue and conquer the world a bit quicker. This time, you turn up in Italy for the first time and suddenly there's thousands of people at the airports because they've seen them on Twitter and Facebook and YouTube and they've watched their videos and they feel like they know them already."

Band member Zayn Malik added that the film gives an accurate portrayal of the music industry in this technological age where everything is online and immediate: "If you watch the film you get an amazing insight into what nowadays the music industry is all about."
