Robbie Coltrane has been hospitalised.
The 64-year-old actor - who played Rubeus Hagrid in the 'Harry Potter' film franchise - was immediately admitted to a medical facility in Orlando after getting off a flight on Thursday (29.01.15) reportedly suffering from severe flu-like symptoms.
A representative for the star has told gossip website TMZ that paramedics met Robbie as he landed in the US city, where he is due to visit a 'Harry Potter' convention, from London and he is expected to remain in hospital overnight.
Robbie is said to have started feeling unwell during the British Airways flight, which Michael Gambon - who played Professor Albus Dumbledore in 'Harry Potter' - was also thought to be on.
In 2012, the star was aiming to shed eight stone so he could undergo a knee operation in the US to fix an old rugby injury which left him in severe pain.
The 'Brave' actor previously said: "It's very painful. You can take painkillers but then you forget what your name is.
"The long-term plan is to have it done in America but not until I've lost another four stone."
The cartilage in the star's knee had broken up so surgeons were due to replace it with teflon.
