Scottish actor and comedian Robbie Coltrane will be "fine", says his agent, after the Harry Potter star was taken ill on a flight to Florida.

The 64-year-old was rushed to hospital upon arrival in Orlando after he suffered flu-like symptoms during his journey from London.

His agent Belinda Wright confirmed on Friday that he was still receiving treatment and would remain in the medical facility for the coming days.

"The prognosis is that he is going to be fine," she said.

As a result, Coltrane has been forced to pull out of an appearance at a three-day Harry Potter convention.

A statement from Warner Bros says: "Robbie took ill last night and is getting the rest he needs to feel better. We are sorry he cannot be with us this weekend and look forward to seeing him up and about soon."

Michael Gambon, who played Professor Dumbledore, Luna Lovegood actress Evanna Lynch, and James and Oliver Phelps, who played the Weasley twins in the wizard franchise, will attend the event.
