The Canadian star has come a long way since he sealed his place in pop culture with his role as time-travelling Marty McFly in Back To The Future and his career has gone on to span more than five decades.
Fox started as a child actor on TV and later became a poster boy for the 1980s with a role in hit show Family Ties, as well as his star turn in the time-travel franchise and parts in popular movies such as 1985's Teen Wolf.
He turned back to TV in the 1990s with a lengthy stint on hit sitcom Spin City, before bowing out to spend more time with his family following his diagnosis with Parkinson's disease. He has become an active campaigner for other sufferers in recent years and been lauded for his extensive charity work.
