PHANTOM OF THE OPERA star Emmy Rossum feels lucky to have wrapped disaster film POSEIDON in one piece - she was the only lead cast member healthy at the end of the underwater shoot. Rossum and co-stars Kurt Russell, Josh Lucas and Mia Maestro all spent six months in huge water tanks filming the POSEIDON ADVENTURE remake and they all were forced to check into hospital with illnesses, cuts and bruises. Unscathed Rossum explains, "This was the most dangerous film I've worked on. Kurt got pneumonia, Josh broke 10 tendons in his right hand, a little boy got a concussion, and Mia went to the hospital with a head injury."
