None.

Eddie can get somewhat angry at times, especially about Marley.

The Ghost of Christmas Past (actually Eddie's father) punches his way through a television screen, causing smashed glass to scatter across the room. No blood is seen, however (because he is a ghost).

Some slight swear words are used, especially when Eddie gets angry about something. Nothing too strong, however.

People drink alcohol at a pub during several scenes in the film.

The scene where Eddie's father (the Ghost of Christmas Past) punches through the TV screen can startle some smaller children.

Eddie becoming angry can scare some viewers, especially children.

(SPOILERS AHEAD)

The scene where Eddie is trying to save a young homeless girl from dying of hypothermia can be upsetting, which may only be worsened by Eddie later finding out he was too late and she has died.

The scene where Tiny Tim dies in front of his parents can badly upset some viewers, especially people who have experienced the death of a loved one or children who are afraid of dying (such as those with cancer). Seeing Tiny Tim's parents mourn his death can also be upsetting.

The whole scene with the Ghost of Christmas Future (actually Eddie's son) can be very upsetting, especially when Eddie comes across his own grave and desperately begs the Ghost that this will not be his future.
