Loved it -- What a charming movie... but not in a quaint sort of manner. Maggie Smith does a wonderful job of portraying Margaret, sometimes called Mary, a homeless and extremely religious woman who was once a well-educated and classically trained pianist. An incident in her past continues to haunt her and keeps her trapped in a world of delusions and paranoia. This is a brilliant glimpse of life and mental illness as presented through the narrative of a playwright, Alan, who observes rather than interacts with his world. Margaret ends up moving her van into his garden and Alan won’t say no. Together, this very odd couple, with his introversion and her eccentric behaviors, create a memorable relationship no one would have imagined. The ensuing dialogue is lively, entertaining and memorable. I'm very happy I stumbled across this "mostly true story". I thought it was well written and beautifully performed.
