Oscar-winning actor Jim Broadbent revisited the agony of watching his mother battle Alzheimer's disease to play a man afflicted with the condition in a new drama.
The Harry Potter star takes on the role of an Alzheimer's sufferer in Bbc drama Exile, and has revealed he drew on personal experience to accurately convey the horrors of the illness.
He tells Britain's The Guardian, "It was upsetting when mother was ill; in a way that was more upsetting than any acting will be. But you know, you just use all that. You remember what was painful about it."
In 2002, Broadbent won a Best Supporting Actor Academy Award for his role in Iris as John Bayley, an academic who watched helplessly as his wife succumbed to Alzheimer's.
