The documentary-maker behind Leaving Neverland has opened up about the filming process, revealing that one heart-rending scene was added into the two-part programme at the last minute.

Dan Reed's documentary, which aired on Channel 4 in the UK and HBO in the US earlier this year, featured in-depth interviews with Wade Robson and James Safechuck, two men who have accused Michael Jackson of grooming and sexual abuse – claims the late singer always denied.

Speaking to IndieWire in the light of Leaving Neverland's Emmy nominations, Reed explained that one scene involving Safechuck and a jewellery box was filmed "more than a year" after their first main interview.

In the scene, James opens up a jewellery box that he alleged Jackson gave him in return for sexual favours. In the devastating scene, Safechuck claims that one item of jewellery was given to him as a "wedding ring".

Talking through the scene's timeline, filmmaker Reed said: "It took him a long time [to find the box]. The house was not big. He found it eventually, and we went back to the location, for continuity, and he sat down and opened this box."

Calling the moment "incredible", Reed continued: "It was like opening up some kind of physical memory. Literally his hands started to shake and he became short of breath, overwhelmed by feelings that washed over him from the past, the intensity of emotion when he took out the ring when he got married."

Last month, it was announced that Leaving Neverland had been nominated for five Emmy Awards, including Outstanding Directing for a Documentary/Nonfiction Program and Outstanding Documentary or Nonfiction Special.

The Jackson estate has denied the claims made in the documentary and criticised the film when it first premiered at the Sundance Film Festival.
