Marion and Arthur are an oddly matched couple. Marion (Vanessa Redgrave) is a sweet old lady and Arthur (Terence Stamp) is a nasty and thoroughly unlikable old misanthrope. Marion is also dying from cancer. However, this isn't destroying her spirit and she spends what time she has left singing with a senior center choir. As for Arthur, he's very sad she's dying, as he does love her but he shows absolutely no love for anyone or anything else.
When Marion dies, Arthur is understandably lost and alone by his own choice and actions. However, the leader of the choir, Elizabeth (Gemma Arterton) makes an effort to try to connect with this old jerk. Eventually, she does and after a while she even gets him to come to choir practice. But he's still proud and a grouch. So what's next?
The film is enjoyable and it's a two or three Kleenex sort of film. However, based on my own personal experience with family and as a psychotherapist, Arthur's change came way too fast and it was hard to believe a 70-something old man would that suddenly stop being the creep he was his entire life. I think the film would have been more memorable and effective had the change been much slower in coming. But, if you can ignore this, it is a nice film. By the way, I noticed that the summary called this movie 'hilarious'. Whoever wrote that has a very sick sense of what's hilarious!!! It's mildly funny in parts but is really NOT a comedy.
