Robbie Coltrane, who is best known for his role of Rubeus Hagrid in the Harry Potter films, has been taken to a hospital after complaining of flu-like symptoms while on a flight heading to Florida. 

The actor was heading to Orlando for the "Celebration of Harry Potter" convention that is taking place at Universal Studios' Wizarding World of Harry Potter.  He was making the trip with co-star Michael Gambon, who played Dumbledore in the film.

Coltrane was admitted and will be staying overnight for treatment.
