As time travelling High School student Marty McFly he gets a glimpse of himself and the children he is yet to conceive in Back To The Future Part II.

Stepping out on Friday, Michael J. Fox was accompanied by oldest child Sam – who looked uncannily like his famous father as they attended the Michael J. Fox fundraising golf tournament in Burnaby, Canada.

The 25-year-old bore a striking resemblance to Fox in his 80s heyday, the only difference being the striking height advantage he had over the diminutive star.

Fox, 53, was in good spirits while sharing a joke with Sam – one of four children with wife Tracy Pollan – as they made their way across the course.

The actor, who rose to fame on Family Ties and went on the star in the Back to the Future movies, was diagnosed with Parkinson's disease in 1991.

While he has struggled with his fate over the years he previously said he wouldn't change his diagnosis even if he could.

'If I walked into a room with God or Buddha or Bill Gates or Sergey Brin or whoever could figure out a way to fix it for me, I don't think I'd do it,' he told Rolling Stone.

‘Because I wouldn't have gone through what I've gone through and I wouldn't have had the experience I've had, and I can still do my s**t. At the end of the day I can still do a show. So what have I lost?'

'The point is, we all have our bag of hammers. We all have our own s**t. It's like the parable about this circle of people and everyone takes their worst problem and puts it in the middle and they all get to choose one to take back – and they all end up choosing their own.

‘And that's kind of it. You'd always take your own problems back over someone else's.'

After a multiple year absence from a full time sitcom, the Family Ties star made his return to television with NBC's The Michael J. Fox Show last year.

'I like the idea of having started playing the son on a family show,' he said. 'Then an adult in a workplace, and now playing a middle-aged father at home. It's nice – it's a good arc.'

The actor is somewhat of a medical anomaly. He was told that he would have to step away from the big and small screen within 10 years of his original diagnosis.

'I just don't tell myself that I can't do it,' he explained. 'Then I just do it. A show is easier to regulate than life.

There's no surprises, really. You know what you have to do in a given day, and you rest and medicate accordingly. I'm shocked at how much easier this is than I thought it would be.'
