One Direction: This Is Us had its highly-anticipated world premiere in London on Tuesday.
Harry Styles, Niall Horan, Liam Payne, Louis Tomlinson, and Zayn Malik celebrated the release of their documentary movie with a big red carpet extravaganza, film screening, and after party.
Also on hand: the project’s director Morgan Spurlock, the head of 1D’s label Simon Cowell, and — oh, yeah — thousands of screaming fans.
