One Direction ‘This Is Us’ movie premiere generates 3.9 million tweets

Some fans camped out for three days ahead of the London screening of the new film

The premiere of One Direction‘s movie This Is Us generated 3.9 million tweets last night.

The figure of 3.6 million tweets was divided up between two million on the premiere itself, which saw the band attend a screening of the film in London’s Leicester Square, and a further 1.9 million tweets appearing on the hashtag #1DMoviePremiere, set up in conjunction with the event.

Four thousand fans lined the streets outside the Empire cinema in central London, squeezing into specially-built pens. Some fans lined up for three days to get the best position and meet the band while hundreds of other fans crowded around the square’s perimeter hoping to see their heroes.

Simon Cowell was also in attendance at the premiere of the Morgan Spurlock-directed film, confirming to reporters that he is set to be a father. Speaking to BBC News on the red carpet, the X Factor mogul said: “I’m proud to be a dad. It’s something I hadn’t thought of before, but now I know I feel good about it.” Cowell is having a child with New York socialite Lauren Silverman, the wife of real estate mogul Andrew Silverman, who is believed to be a personal friend of Cowell’s.

Meanwhile, The Who‘s Pete Townshend recently denied claims that the band wanted One Direction to withdraw their new track ‘Best Song Ever’.

A Twitter storm erupted earlier this month after a review of the boyband’s song suggested there were similarities between ‘Best Song Ever’ and The Who’s classic track ‘Baba O’Riley’. One Direction fans immediately took to the social networking site in order to respond to unsubstantiated claims that the rock group wanted to have the song deleted.
