In Love Actually, Bill Nighy plays rock and roll legend Billy Mack who records a Christmas variation of The Troggs' classic hit "Love Is All Around". Although he thinks the record is terrible, Mack promotes the release in the hope it will become the Christmas number one single--which it does.
When George is barreling down his tunnel of despair, he arrives home and accidentally pulls loose the top piece of his bannister. This is evidently something that happens all the time at his old house, but he finds it especially irritating in the middle of an epic financial crisis. The broken bannister reminds him of everything he doesn't have. Later, when he gets his life back, his attitude changes. Now, he's able to appreciate everything in his life, including the flaws. This time, when the bannister comes apart, he kisses it before putting it back together.
