Trivia: Any viewers outside of Britain might not get the joke when Billy Mack isn't sure which one is Ant or Dec. They are very well known in the UK, and dominate Saturday night telly. The joke refers to the fact that even though they are popular, a lot of people don't know which one's which.
Trivia: Billy Bob Thornton agreed to appear in the movie without having seen the script. On the day of shooting he told director Richard Curtis that he was scared of Benjamin Disraeli's facial hair, and as such wouldn't be able to do the scene in Ten Downing Street because there was a picture of him on the wall. Curtis told him to keep his back to the picture throughout the scene, which he does, although you'll notice he looks quite nervous.
Trivia: Alan Rickman and Hugh Grant, both stars of this movie, attended the same private school in Hammersmith, London.
Trivia: The song Billy Mack is covering ('Love Is All Around') was the theme song for one of writer/director Richard Curtis' earlier films, 'Four Weddings and a Funeral'.
Trivia: Billy Mack, Sam's girlfriend Joanna and the friend who sings "All You Need Is Love" at the wedding, all sang the songs you hear in the movie themselves. The director thanks them for doing that in the booklet in the soundtrack.
Trivia: The short interchange between Colin and the caterer at Peter and Juliet's wedding was originally a scene that was cut from the final version of Four Weddings and a Funeral. Richard Curtis liked the dialogue so much that he injected it into Love Actually.
Trivia: This is not a mistake as such, but in real life the DJ who introduces 'Jump' (where Hugh Grant dances through No. 10) is Jo Whiley, who has a Radio 1 show on weekdays from 10am till 1pm. At this point in the film, though, it is dark outside, so she is not broadcasting in her usual slot.
Trivia: Hugh Grant and Thomas Sangster are related. Hugh Grant's grandmother was Thomas' great grandmother's sister. DVD commentary.
Trivia: 'Pat the Housekeeper' who is introduced in the first scene in 10 Downing St is played by the director's mother-in-law. DVD Commentary.
Trivia: The girl who sings at the end of the school play sang so beautifully, the audio dept had to add breaths as deliberate mistakes to her singing. This was so the audience would believe it was her actually singing. On DVD commentary.
Trivia: The real Christmas No. 1 in the UK in 2003 was Gary Jules' downbeat cover of the Tears for Fears hit "Mad World" from the film "Donnie Darko" (2001).
Trivia: Rowan Atkinson was originally meant to be an 'angel of love' - he was meant to help all the movie's characters find their love (e.g. he helps Sam by distracting the airport employee). He was also meant to walk away at the end and fade away, but the writers thought this too complicated and decided to keep him as a simple shop assistant. DVD Commentary.
Answer: No, Keira Knightley's character is not in love with the best friend; her kiss is one of compassion and affection, not love. Richard Curtis mentions this on the DVD commentary - he says something about Juliet being the sort of girl who would be used to men falling for her and treating them gently and kindly, which is what she does here.
