Magic can be a dangerous business, and the job of a school nurse at Hogwarts must be unlike working in any other school in the world. Only the best need apply, and Madam Pomfrey certainly fits that description. Being a little gifted in the ways of magic herself doesn't hurt; every school nurse should be able to attend to basic bumps and bruises, but Madam Pomfrey can fix bones like they'd never been broken to begin with.
Experienced performer Gemma Jones brings a lot of charm and a twinkle in her eye to the part. She has been a regular face on television screens in Britain since the 1960s, and she can count appearances in the "Bridget Jones" franchise as being among her major successes. Acting runs in her family; her father Griffith Jones was a much-celebrated performer who once shared a stage with Laurence Olivier.
