Bruce Willis is considering taking legal action against Apple.

The 57-year-old actor wants to leave to his huge digital music collection to his daughters - Rumer, 24, Scout, 20, and 18-year-old Tallulah, whom he has with ex-wife Demi Moore - after he dies but iTunes customers are only allowed to "borrow" tracks rather than own them outright.

Digital campaigners Open Rights Group are backing Bruce in his challenge. "You can't resell downloads to friends - and are not allowed to leave them in your will. It's great that Bruce Willis is challenging it," said Jim Killock, of Open Rights Group.

Bruce - who also has five-month-old daughter Mabel with wife Emma Heming - has spent thousands on his music collection, which reportedly includes songs by The Beatles and Led Zeppelin, and downloaded his tunes onto "many, many iPods." The Sixth Sense actor is thought to be thinking of asking his legal team to suggest to Apple that family trusts could be the "holders" of his downloaded music.

Apple is able to freeze the iTunes accounts of anyone it believes is passing on music to other people and it doesn't allow them to transfer songs to mp3 players other than the company's iPods.
