"What If" is a song performed by English actress Kate Winslet, recorded for the animated film Christmas Carol: The Movie (2001).

Winslet provided the voice of Belle in the feature, which is based on the Charles Dickens classic 1843 novel and also stars Nicolas Cage, Jane Horrocks and Simon Callow.

News that Winslet was secretly recording the one-off single to vie for the 2001 UK Christmas number one spot was reported in the Daily Mirror.

"[5] British trade paper Music Week wrote that Winslet could sing the track well but noted that her divorce from Jim Threapleton would make the lyrics less "poignant".

[6] An accompanying music video, which was directed by Paul Donnellon and produced by Chris Horton, shows Winslet walking around an old Victorian house, haunted by the ghost of a girl, along with clips from the film.
