Corrected entry: When the man's phone goes off while he is playing the piano, there is a monophonic sounding text tone. That phone is a Nokia 6100, and the tone should have had a more polyphonic tone to it.
Corrected entry: When the old woman is sitting in her flat, the opening credits of 'The Good Life' is on TV. However, the theme tune playing is totally different to the correct tune. They weren't allowed to use the real tune, but it's still a mistake.
Correction: The music used is a song called "Good Life" by the group Inner City. It is not a mistake, but rather an intentional joke.
Correction: Polyphonic phones can still be used to download monophonic tones. My phone enables real sounding ringtones yet I still have my old monophonic tones.
