A new documentary on actor Michael J Fox recounts his story - including his rise to fame, his stellar career and his diagnosis with Parkinson's disease at 29.
The film - 'Still' - incorporates documentary, archival and scripted elements, with Fox's story in his own words.
It has an Irish connection in editor, and Donegal-native, Michael Harte.
He told Screentime with John Fardy his love for Fox goes back to his teenage years.
"It was 'Back to the Future II', it was the first film I saw in the cinema in Letterkenny," he said.
"I had no idea what was happening because I hadn't seen the first.
"So it didn't make any sense to me, but I was kind of mesmerised - especially by the future scenes of him, and the Hoverboard and all that kind of thing.
"A week later then I rented 'Back to The Future'; and then realised I had six months to wait until the third one came out.
"The rest is history, I just fell in love with the movie.
"The older I get, the reason I think the film works more than anything is because of his performance".

"We had a version of this movie which was just archive," he said.
"We started in the edit; we normally do the edit last, but the film began in the edit where we looked at all the archive with him.
"All his audiobooks, all of his movies, we looked at 'Family Ties'.
"I got excited as an editor - I was like, 'We can tell this entirely through archive'".
'The best interview I've ever had'
Mr Harte said when they decided to interview Michael himself, this all changed.
"[Director Davis Guggenheim] decided to interview Michael J Fox to fill some gaps - what we thought were the gaps of the documentary at the time.
"He shot a four-hour interview with him one day, and rang me and said, 'You should look at this'.
"I watched that interview in one go for four hours; it was easily the best interview I've ever had in an edit.
"I was shocked at how good it was, and how funny he was and honest.
"I rang Davis and I said, 'I think you've found the heart and soul of the movie here'.
"Everything else that we've done is secondary to this, [it] needs to support this interview: this is the film.
"That was a real moment in the edit when we realised that".

"I get nervous at the best of times showing anybody a cut of any film I work on," he said.
"When you meet Michael J Fox and say, 'This is what I consider to be the best hour and a half of your 60-year life - here's all the things I've cut out', it's quite a way to meet someone.
"I've kind of gotten better with my nerves over the years when I'm working.
"That one was on a different level," he added.
'Still' is in select Irish cinemas and on Apple TV.
