DVD: I've Loved You So Long, Rental & Retail, (LionsGate)

Kristin Scott Thomas has her best-ever role in this French drama, playing a taciturn woman who comes to stay with her sister, Elsa Zylberstein, after a lengthy separation. Zylberstein and her family all have their questions about the stranger in their home, and so does the viewer, but 'I've Loved You So Long' doesn't answer them straight away.

It's an impeccably paced mystery which offers up its secrets piece by piece, just as Scott Thomas's character thaws out drip by drip.
