I haven't watched it before now, although it's been on my 'want to see' list for ages.
And the striking resemblance that Paul Bettany bears to an ex is quite worrying. The more I think about it the more I can see the similarities in physical appearance & mannerisms. Same colouring, same build, same physical characteristics. Scary.
And the ex & the above actor are the only blondes I've ever found remotely attractive. Very weird.
It's from the same people as Love Actually so it's no surprise I like it so much but, if you haven't seen it then I recommend it if rom-coms are your thing :o)
