An intentionally uncomfortable biography of the cellist Jacqueline du Pré, who died of multiple sclerosis at 42. Always brittle and self-willed, Jackie (Emily Watson) is driven to greater eccentricity and isolation by her rivalry with initially more talented sister Hilary (Rachel Griffiths). Only fragments of their lives are on display here, but it's enough to underline what a talented and difficult person Jackie was. All the same, debutant director Anand Tucker's device of telling parts of the girls' story twice over doesn't work too well, only adding weight to a narrative that's already becoming sluggish in its second half. Watson seems to have problems with the eccentric speech patterns of the hard-cursing Jackie (although her cello 'performances' are amazing), leaving the subtler shades of Griffiths' obsessively selfless sister to steal the show.
