Hollywood actor Johnny Depp has donated $500,000 (GBP1 million) to the London hospital that saved his daughter's life. The star was so grateful to the staff at Great Ormond Street children's hospital for treating eight-year-old Lily-Rose last year (07) he felt compelled to write them a large cheque. The youngster was admitted to the medical centre last November (07) after contracting the life-threatening E.coli bacteria which caused her kidneys to fail. Depp and his family were in London while he was filming Sweeney Todd: The Demon Barber of Fleet Street when Lily-Rose was taken ill and production had to be halted while the actor maintained a bedside vigil for his sick daughter. Lily-Rose recovered and was discharged nine days later, and Depp has been quick to praise the staff at the hospital for all their efforts. He says, "It was the most frightening thing we have ever been through. It was hell. But the magic was that she pulled through beautifully. "Great Ormond Street was terrific, a great hospital." To show his gratitude Depp offered a substantial donation and invited five doctors and nurses who cared for Lily-Rose to attend the party for Sweeney Todd last week (beg07Jan08). Disney, who made Depp's Pirates of the Caribbean films, has also donated $20 million (GBP10 million) to Great Ormond Street to help fund redevelopment of the hospital site. Lily-Rose is Depp's daughter by long-time girlfriend Vanessa Paradis. The couple also has a son, Jack, who is five.
