One Direction have been talking about the bits which didn't make it into a documentary about them, One Direction: This Is Us.

They told Newsbeat entertainment reporter Chi Chi Izundu they wished the US tour had made it in but it didn't fit in with the schedule.

Harry also revealed a rather unusual moment involving Niall and a couple of animals which failed to make the cut.
