Pirates of the Caribbean superstar Johnny Depp has vowed to help a British teenage car crash victim who has spent over five months in a coma.

17 year old Sophie Wilkinson from Southampton, England, was involved in a near fatal car crash last year and has since been in a coma.

Depp is Sophie's favourite actor and her parents wrote to the Hollywood star in hope - but it is reported that the actor was touched by the sad story and will try and do as much as he can.

Depp has agreed to record a voice message for Sophie which will be played to her and has also agreed to try and visit her at Southampton General Hospital.

Sophie's father Andrew said, "We are looking for the key to wake her up, so we wrote to Johnny and he said he would do the recording in the voice of (his Pirates of the Caribbean character) Jack Sparrow.

"Only this week Sophie moved her right leg, which she has never done before.

When we got home my wife and I were jumping for joy!"

MTV wish Sophie all the best.
