Films about elderly people moving house because they can't handle the stairs don't come along very often. It's a tough concept to pitch to a studio executive. But silver surfers searching for an apartment with a lift clearly rang true for somebody as it is the story of Ruth & Alex - and I know a lot of people who will really enjoy it.

I did, and largely because the long-time married couple of the title are played by the inimitable Diane Keaton and Morgan Freeman. Together they play the sort of pair you would pick for parents as they are charming, erudite, hip enough to move to Brooklyn when it wasn't fashionable and blissfully content in their own company. Director Richard Loncraine shows us how Alex, an artist, and Ruth, a teacher, meet through a series of flashbacks that include her family disapproving of their interracial relationship. Tame, but reassuringly familiar, much like the old apartment Alex is reluctant to leave and their ageing dog who is in a bad way at the over-priced vets in Manhattan. Until you have gone flat-hunting in New York it is impossible to imagine the madness that takes place, but Ruth and Alex's open house organised by their realtor niece (Cynthia Nixon) gives a hint of the insanity. The film has a European flavour, but lacks the courage to truly embrace what it has ignited and even the dog makes it through for a final bow. That said, it is perfect Sunday night cinema for couples who have stayed together and offers insight to anyone thinking about selling the family home in Chigwell to move to a flat in Bushey.
